on May 22nd my boyfriend and I had unprotected sex (I know my mistake), he said he might have finished inside me, however when I stood up normally dripped out.. so is it possible he just thought he finished and didn't? Also the next day within 12 hours of this happening I took plan B one step ... it was on the 9th day of my cycle so I still have about a week till my expected period, I haven't had any side effects of plan b but I do have some white discharge.. did plan b work ?
