Irregular bleeding

Melissa

Heres a pic to help see...So,, I miscarried in nov. Had a period in Dec. I'm in a program, and it recommended I'm supposed to get birth control. So I started my pack the 3rd day of my period.. Well my Jan Period was late because I assume I started the birth control in Dec. And I said no way I'm not dealing with that I like my periods and it was like almost 2 years of none from my previous pregnancy.(I breastfed). My husband and I said screw it and I stopped the birth control on Jan 8. I get my "period " Jan 12-18 and this week I get my "period" again for the last four days light /medium I am so confused. I've never really had mid cycle bleeding g... I'm supposed to ovulate next week is it bleeding due for ovulation? Could one month and 4 days of BC cause this irregularity? I'm worried it's something more. I don't think it's implantion bleeding it's too heavy and long for that (also though we had sex 27 of Dec and I was supposed to ovulate Jan 4 - took BC until Jan 7) it's been sooo long since I used birth control if any one can help I'd be so greatly appreciated. Or experience something similar.
