I have the app "my cycles" and it said that was when I was suppose to ovulate.
It's rare but what makes you think you were ovulating while on your period?
I looked it up.. it said it was rare but you can ovulate on your period.
i would say the chances are real low.. 1, yur on birth control nd 2, yu were on yur period... nd yu dnt ovulate while on yur period its after wen yu ovulate... to ease yur mind juss test ina couple weeks
