Have you heard of Natural Family Planning (NFP)?


It’s a Fertility Awareness Method that can be used either to prevent pregnancy or to achieve pregnancy. With NFP, you observe the signs or symptoms of fertility and then you avoid sexual activity during that time if you want to avoid pregnancy, or you have sexual intercourse during that time if you want to achieve pregnancy.


What sort of fertility signs do you look for?

  • Basal body temperature. Your body temperature rises slightly when you ovulate. So to use this method, you take your body temperature every morning when you first wake up. Then you plot the daily temperature on a graph. As you do this, you will see patterns in your body temperature throughout your monthly menstrual cycle. You can predict when you are ovulating based on your body temperature and avoid sexual activity during those days.


  • Cervical mucus changes. Cervical mucus changes in texture, color, and amount throughout your menstrual cycle. To use this method, you feel and look at your cervical mucus every day and chart a description of the mucus. You’ll need to chart the mucus every day for a month or two before you can rely on this method to prevent pregnancy. A medical professional or NFP counselor can help you know what your cervical mucus looks like when you are most fertile in your cycle.


  • Cycle length. This is also called “The Calendar Method.” You keep track of your menstrual cycle on the calendar and count the days in each cycle. For this method to be effective, you need to count the days for at least 6 cycles (or 6 periods). After you know how many days each cycle is, you can use a mathematical equation to figure out which days you’re most likely to be fertile. Then you can avoid sexual activity on those days if you don’t want to get pregnant or have sexual intercourse on those days if you do want to become pregnant.


Some people keep track of only one of these signs of fertility. But to be most effective, you would need to track all three signs of fertility.


How effective is this in preventing pregnancy? According to the Centers for Disease Control (CDC), out of every 100 instances of people using NFP, there are approximately 24 unintended pregnancies each year. So that makes NFP about 76% effective in preventing pregnancy.


Does NFP prevent Sexually Transmitted Diseases (STDs)? No. NFP can only be used to help prevent or achieve pregnancy. The only way to 100% prevent contracting an STD is to be in a mutually monogamous relationship. This means both you and your partner know for certain you do not have an STD and you both only have any type of sexual activity with each other.


Can I do NFP on my own? NFP is most effective if you do this under the guidance of a medical professional — a doctor, nurse, or counselor who knows NFP very well. This person can help you understand the information you chart (your temperature, the description of the cervical mucus, and your cycle lengths) and interpret the signs of fertility.


Observing and keeping track of all your signs of fertility can be effective in preventing a pregnancy or in helping you get pregnant. Other than the cost of the thermometer and the charts you track all the information on, NFP doesn’t cost anything. But it does require a little bit of daily work, dedication and the decision to abstain from any sexual activity during the days you could be fertile.

If you took the first abortion pill, it’s possible to start wishing you hadn’t. The regret may have hit you immediately, or it might have taken a few hours to realize that you want to continue the pregnancy. Either way, there may still be something you can do: abortion pill reversal (APR) may be an option. The first drug used in the abortion pill regimen is usually mifepristone. If you have taken mifepristone but now want to continue your pregnancy, call the Abortion Pill Reversal Network at 1-877-558-0333 right away. Their Helpline is available 24/7 and can connect you with a medical provider who can administer APR. If You Have Only Taken the First Pill Mifepristone works by blocking progesterone. Progesterone helps maintain the lining of the uterus during pregnancy. When this hormone is blocked, the uterine lining thins, and the pregnancy ends. The second drug in the abortion pill regimen is misoprostol , which causes the uterus to contract and expel the pregnancy. Abortion pill reversal involves giving progesterone after mifepristone in an effort to allow the pregnancy to continue. Don’t Wait for Symptoms Before Calling You may wonder whether you should wait before deciding what to do. But if you want to try to continue the pregnancy, call first.  It’s critical to start the protocol as soon as possible, ideally within 24 to 48 hours of taking mifepristone. However, you should still call even when more time has passed; it may not be too late. A medical provider can determine whether APR may still be appropriate. Does Reversal Always Work? Abortion pill reversal cannot guarantee that the pregnancy will continue. One published study reported ongoing pregnancy rates of approximately 64% to 68% with certain progesterone regimens, but individual outcomes vary. The important thing is to get medical guidance quickly rather than trying to determine your chances on your own. What if You Already Took Misoprostol? If you have already taken misoprostol, contact a healthcare professional promptly and explain exactly what you took and when. You should also seek immediate medical attention if you develop symptoms that concern you or believe you may be experiencing a medical emergency. Make the Call Now Changing your mind after taking mifepristone can be frightening, especially when you’re unsure whether there is still time to act. You don’t need to figure that out yourself. Call the Abortion Pill Reversal Network at 1-877-558-0333 as soon as possible and tell them when you took mifepristone. They can explain whether abortion pill reversal may still be an option and connect you with an appropriate provider. You can also contact Collage if you need someone to speak with while you work through your next steps. We’re here to help you. *Collage does not provide or refer for abortions; however, we do offer pre-abortion screening through our no-cost services. **All abortion information in this blog is based on accurate information at the time of writing.

Seeing another positive pregnancy test after having had a past abortion may bring up memories or emotions from that experience. If you already know you don’t want another abortion, you may be wondering what other choices you have and whether either feels realistic for your life right now. You have time to learn about your options and the available support. Collage is here to give you a place to discuss your circumstances so you can decide what’s right for you. Schedule a no-cost appointment today to learn more about your pregnancy and what your next steps could look like. And read on to learn more about your pregnancy options besides abortion. Consider What Parenting Would Require You may want to parent but have concerns about whether you can make it work. Finances, housing, childcare, your relationship, work, or school can all influence how possible this option feels right now. Before deciding that those challenges make parenting unrealistic, it can help to identify your biggest concerns individually. Some of those concerns may have solutions you haven’t considered yet. Think about the support you already have, along with what you would need during pregnancy and after your baby arrives. Knowing where the gaps are can make it easier to find resources rather than trying to solve everything at once. Learn More About Adoption If you don’t want another abortion but aren’t ready to parent, adoption is another option. Today, a woman making an adoption plan can have a significant role in deciding what that plan looks like. Depending on the type of adoption, you may be able to choose an adoptive family and decide what level of contact you would like after placement. Open, semi-open, and closed adoption offer different levels of communication and privacy. Speaking with a licensed adoption professional can help you understand these differences, your rights, and what the process would involve before you make any commitments. Discuss Your Options in a Confidential Space Having had an abortion before does not mean you have to make the same pregnancy decision again. Your feelings, circumstances, priorities, or perspective may be different this time. If you know you don’t want another abortion, start by learning what parenting and adoption could realistically look like in your current situation. Collage provides a place to talk about your pregnancy and the concerns influencing your decision. We can also connect you with adoption agencies and community organizations that provide the support you’re seeking. Reaching out doesn’t lock you into a specific decision. Schedule a no-cost appointment with Collage today to get your questions answered and explore the options available to you. Collage does not provide or refer for abortions; however, we do offer pre-abortion screening through our no-cost services.
