Hey. I don't know what to do. I am 19 years old and married to a wonderful man. We have been having unprotected sex for awhile and now I think I might be pregnant. I wouldn't care if I was pregnant I would be happy. We both would. But the thing is, I don't know exactly when my period is suppose to start. I have been irregular since I started my period. I'm pretty sure I was suppose to start it already or am about to but I don't know. A few weeks ago, we had sex and he orgasmed inside of me. Lately I have been just exhausted like I havn't slept at all, I have had lower backaches, my breasts seem to be getting larger, my stomache seems to be getting a little larger like I'm bloated, and I have been having light cramps and they are always in the same spot. I am really confused about something too. Since we had sex that night, I have had the "runs" like really bad. I know that when people get pregnant they always complain about being constipated but I have had the exact opposite. Not like period cramps just cramps. I have been craving certain foods really bad. I have had cravings before, but not like this. I feel like I HAVE to have these foods. I havn't been nausious but I have been getting easily nausous in the car and by movements lately. My husband thinks I am pregnant. I'm not sure to think. Should I take a test? When should I take it? I really need help. Any help you could offer would be greatly appreciated.
