... was suppose to get my 7th or 8th shot last month, but do to certain circumstances I was not able to get it. Since my last shot in June of this year I've been having unprotected sex. Last month when I was suppose to get my shot I had unprotected sex but the last two remaining weeks of September I didn't have sex. This week I had unprotected sex more than once. I have not went to the doctor yet. Can u tell me if I might be pregnant?
