Hi, I m 30 years old and I m experiencing vaginal blood discharge. It is more pink than red. Very liquid. It doesn t smell anything else than blood. My last period started on august 2nd and ended on the 5th. I m usually getting my period every 30-32 days. I also have a copper IUD, however it is just about getting expired. 5 years. Now, what happened: - I had unprotected on august 20th. My partner and I were very drunk and had pretty rough intercourse. As I m very sensitive for bladder infection, I was taking a cranberry supplement to help me avoiding to get an infection. So far I don t have a bladder infection. - We are on august 23, and this afternoon I started having this liquid, pink bloody discharge. I also noticed that I go urinate a little more frequently and I m swollen up in the lower part of my belly. I DON T HAVE: - I don t have rash, nothing is red, no pain, no lumps or bumps ------ My questions are: 1- Is pregnancy possible? and getting spotting just 2-3 days after having sex? 2- Did I get a STI? Would have get symptoms after just 2-3 days? I m not sure anymore about my partner... 3- What else could be possible?
