i got last depo 06/10/2015 and didnt get a full period till 12/31.. on sun. 1/10 i was nauseous and vomited twice. then on tues. 1/12 i realized in the afternoon i had very dark brown discharge. i thought maybe its implantation and i got pregnant. period was always a regular 28-29 days cycle. Now wed. 1/13 i wake up and BD'd and BOOM i was full of blood and have had heavy bleeding and cramping all day weds. and today. one blot clot size of quater (sorry tmi) and then just heavy flow. i tested and it was negative (thinking if so hormones would still show) could i have been prego and had a MC or could i just have a heavy IB flow and still be prego. Im thinking of going to urgent care tomorrow morning but not sure if im over reacting. AND YES IVE HAD UNPROTECTED SEX at least 5 times each of the past 2 weeks. Can someone please get back to me with their most knowledgeable option/advice.
