Ok, i'm four months pregnant as of friday, on saturday, my fiance and I were having sex, and after I started to spot, not a red blood, but a pinkish blood, I went to the hospital, they did a test on the baby's heartbeat and said everything was ok, but i'm still worried that something could be wrong. Has this happened to anyone before??? This is the first time i've spotted since I became pregnant. I'm also getting some cramping, not severe cramps but it's uncomfortable. Any advise anyone?
