How To Use Fertility Awareness Method (FAM) With BBT and YONO For Natural Contraception
You can increase your chances of natural contraception by pairing the knowledge of FAM (fertility awareness method) with records of your nightly basal body temperature (BBT). YONO makes it easier than ever to accurately record and keep track of your BBT, ultimately improving your family planning methods.
What Is Fertility Awareness Method (FAM)?
FAM, or fertility awareness method, is a methodology that focuses on noticeable changes that occur in your body during your menstrual cycle as your hormones cause ovulation and the release of an egg. FAM can be used as a family planning method, either as natural birth control or to help you conceive.
FAM is based on facts we know about fertility, sperm and eggs, such as:
- You typically release one egg each menstrual cycle and that egg can live between 12 and 24 hours.
- Sperm can survive up to 5 to 6 days in the uterus, during which time it can fertilize an egg.
- Women are typically fertile for up to 6 days pre-ovulation and 2 to 3 days post-ovulation, for a total of 7-8 fertile days in each monthly cycle.
Additionally, there are 4 key rules to FAM, which can be used as:
The 4 Rules Of FAM:
#1. The First 5 Days Rule
If you confirmed ovulation via a temperature shift in your previous cycle, you are not fertile the first five days of your period. Despite popular misconceptions, some women are fertile immediately after their period.
#2. The Dry Day Rule
You are not fertile the evening following a dry day or a day with no cervical fluid.
#3. The 3-Day Temperature Shift Rule
You are not fertile the night after your third day in a row of temperature shifts that remain above your coverline. Your coverline is defined as one-tenth of a degree higher than your highest temperature recorded over the course of six days prior to ovulation. The easiest way to keep track of this is through the Yono app, which graphs your BBT for you each day.
#4. The Peak + 4 Days Rule
You are not fertile the fourth night after your peak day of cervical fluid, which is also the last day you will notice cervical fluid.
What Is Your Basal Body Temperature (BBT)?
Your basal body temperature (BBT) is the lowest body temperature your body reaches while you sleep. Since you cannot take your temperature while you sleep, people often estimate their BBT by taking their temperature right when they wake up before they partake in any activity. Rising BBT signals you are ovulating, which is the best time to have intercourse in order to conceive.
Using YONO To Track Your BBT
The best time to take your basal body temperature is before you ever wake up, which can be kind of tricky to accomplish without some help. YONO makes it easier than ever to accurately track your BBT. Skip all of the guesswork by simply wearing the world’s first in-ear BBT thermometer to bed each night. It’s so comfortable you won’t even know it’s there.
While you sleep, YONO tracks your lowest temperature and then stores this information. When synced with your smartphone, it charts your nightly BBT on a graph, showing you exactly when your basal temperature increases and decreases. This provides you with the most accurate way to determine when you are ovulating from the comfort of your home.
As a result of using the methodology behind FAM and your personal BBT chart created by YONO, you can improve family planning methods by having intercourse when your chances for conceiving peak.
