I am 4 days late, as of tomorrow I will be 5. I am on birth control. Jan 7- 10 was my last period. I had intercourse with a male who had a vasectomy on the 16th of Jan. My ovulation dates were Jan. 20-26. On Feb. 4th I had a dark brownish color discharge and I had thought I was going to start my period, this had went on for 2 days. On Feb. 6th I had Intercourse with my current boyfriend. Unprotected. He had done the pull out method. I am not 4 days late, I know that it can be stress, but I have been sleeping almost the whole day every day, weird dreams which involve babies, etc. I am on birth control, and also took a pregnancy test two days ago that came out negative.
