I had Unprotected with my boyfriend June 20th, I then took Plan B the 21st, from there I experienced some spotting around the 26th or 27th. During this time period I had sex with a condom. On the 30th I then received my period, the week I expected it. Very heavy flow for the first 3 days. I'm on my 6th day, my period almost over. But could I still be preganate ???
