I am on the pill and take it daily. I don't take it at the same time every day though. I had a lot of unprotected sex this month where my husband came inside of me. It's 8 or 9 days til my period is due. Today I noticed creamy discharge with a hint of pink in it. I also had super mild cramps with this. It only lasted a few hours then stopped and the discharge stopped as well. I am afraid this is implantation bleeding. This has never happened before. Is it even possible since I am on the pill?
