About 1 month ago, I had unprotected sex with a guy. I did take plan b one step about 9-10 hours later. I had gotten my period when it was due to come about 7-8 day later. Now I am experiencing pain in my pelvis and lower back and two days before that I hate white, cottage cheese like discharge, which has now cleared up. The pain is not constant and is not the painful but it is noticeable. I've checked my temp 3xs and it was 99.2, 98.0 and now 99.0. I was thinking that this could be a yeast infection, but am unsure with the little pains I am feeling. There was no foul smell with the discharge
