Im on the low dose estrogen only birth control pill. This is my last week on it. I was expecting my period on the 8th but all ive noticed was some blood ONLY when i wiped today (10th) is the day i actually had some blood on my pantiliner. The last 2 months i got my period the morning of the 8th and it was normal. I know for a fact im not pregnant but i want to know whats going on with my period?? Saturday will be the last day ill be on these pills btw.
