Okay, so I had unprotected sex, and he DID pull out, but I know that doesn't always work, and two days later I had my period. It was a week early. It has been about 3 weeks since then, and I have gained a little weight, as well as been hungry more, lower back pains, and a little nausea.. Is there any way I COULD be pregnant?
I think you should wait to see if you get your next period.
