About two weeks ago,I dry humped with a guy but we were both naked.. We were moving like we were having sex, but just that his penis was between my thighs.. and when he came, it was on the lower part of my stomach, I stood up immediately, and liked salt and drank water then later I went to clean up. last week, I. started feeling somehow, I had constipation, I couldn't digest food, I was belching frequently and my stomach was kind of big cos I couldn't poop.. I'm scared cs I'm a virgin and I dnt want to get pregnant now.. I tried the sugar pregnancy test, and twas negative. but when I tried the bleach pregnancy test, it fizzled a little and had little foam at the edge
