Question: Is is possible to ovulate while taking birth control pills?


 WineCountryGal - Tue Feb 09, 2010 12:59 am

I have been taking birth control pills for 10 years. I have been taking Mononessa 28 Tablet (or the equivalent generic) for the past 5 or 6 years I think. About 6 months ago I started having bleeding when I have about 7 active pills left. I bleed for 2 to 3 days and then it stops. I have a normal period during the inactive pills. The bleeding I am describing is dark/brownish and clotty almost at times. There is sometimes light cramping associated with this bleeding. There is not a lot of blood but enough that I need to wear a maxi pad. I am concerned that my birth control pills are no longer working and that I could be ovulating. Is this possible?

User avatar Hello,
Women don't develop tolerance to the pill where it becomes ineffective over time, but if the inconvenience is bothering you, a switch to a different pill might be beneficial.

It is possible to ovulate while on the pill (for any woman) but it is unusual and usually associated with missed pills (usually 2 or 3). Taking them as directed in 99% of cases will prevent ovulation.

Best wishes.
