... 1-2 on Sunday) my boyfriend and I have had unprotected sex and he came inside each time. Now, I typically have my periods by the first of every month and, considering I'm taking deposit, I'm not sure if I'm having it or not.. I've felt pain in my back (not usual) and intense cramps in my pelvis, am nauseous (always crampy and nauseous on my period), and I just noticed a tiny amount of white discharge from my left nipple... I've also been peeing a bit more.. Could I be pregnant?
