My boyfriend and I had unprotected sex whereby he did came inside of me. We did this a week before my period and I took the Plan B pills after we had sex. On the week that my period is expected to come, every time I wipe there are dark brownish discharge on the toilet paper/tissue. A couple days afterwards the discharge turned more red but when I put on a pad there's nothing on the pad. However, when I wipe to check if I'm bleeding there will be reddish dark brown discharge on the tissue. Am I on my period or not??????
