Hello, doctor. I had protected intercourse on Friday 17 2013, and my period was supposed to come on Saturday the 25. This morning, on the 26 I wiped and I saw pink, so I put on a pad thinking it was my period. However, I checked the pad 2 hours later and there were spots of dark discharge similar to the kind after a finished period. I have all of the usual symptoms that I get before a period, and the same thing happened on the 19. Does this mean I am pregnant?
