i started BC(yaz) may 11th and stopped may 14th bacause it made me realy sick. after stopping the BC i didnt have a period for 2 months, very irregular for me, naturally i suspected pregnancy but tests came out neg. july 12 i got my period and it lasted 5 days but was very light. then in august in got my period on the 7th and it also lasted 5 days and was normal flow. then this month i got my period on the 3ed and had normal flow the 3ed and 4th then the fifth blood was brown and very light and today the 6th after urinating when i wiped it was a very light tan color and now no bleeding at all just lower abdominal pain not feeling like cramps they feel a little sharper. could implantation have happened during my period or could my period been implantation bleeding even if the first 2 days was normal looking bleeding?
