I have not had a period since September, when I had unprotected sex. In October, I had symptoms consistent with a miscarriage. However, my bleeding was not as heavy as expected, leading me to think that it may not have been a miscarriage. I went to a clinic and was given a pregnancy test which came back negative. They told me to get tested for any STD s and to make sure that if I did have a miscarriage, it was complete and there aren t any complications.
