Question: On BCP, Have breakthrough bleeding same time every month

 Clueless021 - Sun Apr 26, 2009 7:12 pm

I have been on bcp for the last 2 years. I have changed bcp 3 times in that time frame. Before I originally started taking them my period was very regular. I started taking them following my period so every month when I was on the placebo pill it was the same time as my natural period. Unfortunately when switching pills the two times that timing has been thrown off. Every month I have breakthrough bleeding on the same day two weeks after my placebo period-- which would line up exactly with when my natural period was coming. Is this unheard of, my natural period still "coming" while on the pill?

User avatar Hello,
There is no guarantee or completely predictable response to oral contraceptives. You do have natural hormones in addition to the artificial ones in the pill so it is possible to have irregularity that is caused by your own fluctuation. Don't be surprised if throughout your life you see changes in your cycle. It is natural.

Best wishes.
