All right so me and my boyfriend had unprotected sex the 20,22,23,24 of may. My period was the 12th of may. On may 28 I experienced extremely light spotting. It was very light pink and brown. Its been about a week an a half, I took a pregnancy test and it was negative and I probualy took it too early. Just nervus I guess. Based on the dates I gave you and the bleeding, what do you all think? Am I pregnant?

It's certainly possible... see what happens when your next period would be due and test again if need be.
