Hi..
I started BC in Oct as instrusted. Nov 4th I had my period for 5 days. The next week I couldnt stand the side effects any more so I stopped taking it on Nov 11. Nov 12 I started bleeding for 3 days. My ? is which date do I use to predict my next period the 4th or the 12th, and which date would the ovulation be calculated by?

Thanks to anyone who has an answer! I dont like not knowing when to expect AF.
