I took a pregnancy test on April 8th, which was the day my period was due, because my boobs hurt sooo bad. It was a very faint positive line. I took another on Thursday and the line was a little darker positive line. Then on Sunday my boobs no longer hurt and had a negative pregnancy test and then period started. Had it for 5 days and then quit. This week I started with some pink discharge only when I wiped, now its brown, still only when I wipe. Some very mild cramping off and on. Any ideas what is going on?
