So my boyfriend and I had unprotected sex September 3rd and 4th. My period was due on the 7th however it didn't come. We then had sex again about a week later during ovulation and still no period. Yesterday I started experiencing some bleeding but its very light, not like a usual period. I took hpt on the 22nd and it came back negative. I have some symptoms of pregnancy but I'm not sure. Could I be pregnant?
