pregnancy symptoms!!

for the past (almost) two weeks I've been on my period. six days straight, off for three, and now its starting back up again as of yesterday. When the bleeding first started, it was breakthrough bleeding but it was heavy and it didnt stop. now that its started back up again, Im on my regukar cycle. I've had no acne which is strange, unbelievable gas, bloating and cramps. I did have sex without a condom the week before my period started but he didnt ejaculate inside me. I'm concerned because there arent normal symptoms to be happening with me. confused also... help anyone?
