It's been 20 days (august 11th) since I fooled around with this guy I know, I took a digital pregnancy test earlier this morning and it showed a negative result. 18 days ago (two days after sex) I took plan b two-step. Then 5 days after taking plan b i got what I thought was a light and spotty period which lasted 4-5 days, if it wasn't a period- than i suppose it may have been pregnancy bleeding. The bleeding itself was not normal, and did not flow, I did experience bleeding of a dark red color though, not typically pregnancy bleeding- but also shades of brown and pink. Other than the strange spotty bleeding my last period was I believe around august 8, I at least remember bleeding that night. I'm on a serious time crunch to figure this out! Any advice? Thoughts on my situation, could i still be pregnant?
