Hello, I had my period 11/17. Had unprotected sex on the 11/25 and 11/29. I'm irregular but the time it was expected to come I was 4 days late and last 3 1/2 days which is different from7 to 10 days could this had been my last period to pregnancy I am trying but its no rush I just want to know. I been having the same pregnancy symptoms for 3 weeks now and while off period the symptoms are still there. The cramping, fatigue, hunger, peeing a lot when I haven't had a drop to drink to make me go. Headaches backaches emotional all of it except sore boobs. Just a little uncomfortable to lsy on them some times.
