I had my last period on July 17-21, 2016. On July 27, I had protected sex with my bf and also did a withdrawal just to be sure. After few hours, I noticed a white milky discharge on my underwear, and the same discharge occured last July 31. On Aug. 4 I also noticed a sticky discharge. Since last week I was having migraine, but wasn't experiencing any pms symptoms. Since last week I also feel somehow nauseous and bloated. I'm also somehow sentive with smells but still no any pms symptoms. But today, Aug 14, I noticed a pimple in my face, slight cramping and my boobs feel a little tender. Could I be pregnant? I really need to know since I'm already a little paranoid and stressed.
