Ok two months ago I had sex and we didnt use a condom since I was on birthcontrol but then I had withdrawal bleeding on time a couple weeks later but it was bright red/watery with no clots (I usually of some). Its lasted a couple days like usual. Then this month I was getting a little sick at night. Now im on the sugar pills. The first day of the sugar pills ive been getting bad back cramps and got a small blood clot, and thats it. I usually start my period on the 4th sugar pill day so this is early then usual to even start.
