Calendar method used as birth control
Dear Anai,
We have been using the calendar method to avoid pregnancy. I think we may have had intercourse too close to the guesstimated ovulation day. What are our chances?
Thank you,
Busymom
Dear Busymom,
Ovulation predictor kits are far more accurate than any other method for the reason that they focus on hormones in the urine.
Basal Body Temperature (BBT) is a great method as well, but it cannot predict ovulation and the temperature fluctuations from illness or lack of sleep can alter the true results. The BBT method used along with an ovulation kit is a wise idea. You can compare your results easier to determine ovulation timing.
Ovulation calculators online will not give you an exact ovulation day. It is a guide one uses to undertstand the generalities of ovulation itself. So don't worry that it says something your predictiors and BBT did not.
From the dates you have given me, there is maybe a 15% chance that you are pregnant. Sperm are able to survive in the fallopian tubes for up to five days (others have recorded seven days).
If you are not pregnant this cycle, begin using condoms. If you are able to get on the pill - do it. The calendar and pull-out method simply do not work.
Thank you for writing!
