Charting your Peak Day

You will want to look for your peak day when you are charting. You will know it is your peak day by the days that follow it. Once you see the shift from wet fertile cervical mucous to dry cervical mucous you will know that your peak day has occurred. Mark your chart with a P on the last day you see fertile cervical mucous. Then mark the following four days of dry cervical mucous with 1, 2, 3, 4. Once you have seen four dry days you can assume you are no longer fertile.

Peak Day and avoiding pregnancy

If you are trying to avoid pregnancy, do not have intercourse until four days after your peak day. Your peak day usually occurs the day before ovulation or the day of ovulation. Since your egg can survive for about 24 hours you will not want to have sex until around four days after your peak day to avoid pregnancy.

Peak Day and trying to conceive

If you are trying to conceive you will want to start having intercourse before your peak day. After your period ends you will notice an increase in cervical mucous. The typical pattern is tacky cervical mucous, that turns to creamy, that changes to clear stretchy egg white looking cervical mucous. While it is true that you are looking for egg white slippery cervical mucous to indicate ovulation, it is a good idea to start having intercourse before you see this. The reason behind this is that sperm can last up to five days and your egg can only last 24 hours. If you wait until the day you see slippery egg white mucous, you only give yourself a one day opportunity to get pregnant. If you have sex prior to ovulating as well you will increase your chances of getting pregnant.
