Hi everyone, I never done this before, but I will try my best to explain my predicament. I started my period on Wednesday the 1st of July by that Sunday on the 5th I was off. On that very same day me and my boyfriend had unprotected sex in which he excrected semen in me. I have a very hectic work schedule so by the time I took Plan B it was already 5 hours past the 72 hour marker. For the past two weeks I have been experiencing alot of changes, such as sore and swollen breast, nausea, bloated, and mood swings. All these symptoms are common to my period, which should start by the end of this week. I took two pregnancy test and both were negative. The reason for this post is that last night I noticed red brownish discharge when I went to the restroom and I started having some light cramping and feeling exhausted alittle bit afterward. I also been having some back pain. I thought it was my period,but I only see red brownish discharge when I use the restrooom. I would really appreciate all the help and advice I can get. Thank you.
