I had protected sex 7 days ago (Friday) but the condom slipped off of him as he pulled out although it was quite far out of me. I took the morning after pill (Madonna) that Sunday morning very early. It's been 5 days since I took the pills and this morning I had a very tiny amount of brown spotting when I went to the bathroom but not enough for me to need to wear a liner or pad and has vanished now. I am expecting my period in the next 8-9 days. Should I be concerned or is this normal, I am very stressed.
