Hi there, thank you for posting your question on Ehealthforum. This is not intended as a substitute to visiting your own doctor.
It's difficult to know how to advise. But if only for your own peace of mind I think you are going to have to have an STD screen and a pregnancy test. In the meantime it would be as well if you boyfriend used condoms. You will be fine.
Dr Andrew Rynne.
