Ok so my period was supposed to start today but when I went to the bathroom around 11:30am, there was a bit of pink blood with tiny red spots when I wiped so I put a tampon in. When I went to use the bathroom later in the day, I took out the tampon and there was only a tiny bit of pink. Just to be safe, I put another tampon in. When I peed a few hours later, there was nothing. My boobs have been hurting on and off for the past two weeks (which usually only happens two days before my period) and I've been a lot more emotional and sensitive to smells. August 10th, I had unprotected sex with my boyfriend and he came in me. I took 2 pregnancy tests three days ago and one came up "?" and the other was negative. What do y'all think?
