Hi,
my periods are fairly regular that start between the 28th-2nd of each month. On May 14, I had sex with my boyfriend and he ejaculated inside. The condom was half off but he said that the semen was still trapped inside the condom. I took the plan B pill an hour after we had sex, just in case semen actually did leak out.

Now it is the 31st, and all day I was spotting.. I think. It wasn't enough to wear a pad. When I wipe, there isn't much blood but when I pee and then wipe, it's more like an actual light period. Also this is too much info but the toilet bowl does look like a normal period.

Does this sound like implantation bleeding or just a very light period due to the plan B pill? Also, this whole month I have had a change in diet, have been exercising daily after a 2 yr hiatus, and the boyfriend was in the hospital for a few days so I was stressing. I also have a much more hectic work and school schedule, do you think this is all causing my inner environment to be all screwed up?
