So I'm really sketched out and I don't know why. I had sex about 3 weeks ago we used a condom and he took it off and put it back on and pulled out and finished. I had my period last month on the 18th. I took 3 pregnancy tests and they came out negative but I don't know if it was to soon to take them. I don't know if I've been have period symptoms I've been moody I guess and have been crying kind of but I don't know if that's just because I'm stressed out. Please help.
