Okay so for roughly three months I purposely skipped my borth control placebo pills, then on the fourth month my period suddenly returned, for about three weeks I bled and then it stopped for a week, i continued taking the pill as I would regularly would (however I will now remember why I shouldnt skip periods) during that week without the bleeding I had sex twice both with condoms and obviously the pill, but this week, 1 week roughly after having sex my bleeding has returned, I've heard of implantation bleeding but I was wondering if it could be my body being out of sync due to me screwing around with my cycle, its not the usual bleeding its thick and brown like the beginning or end of a period, any info you might have would be deeply appreciated
