On 16/12 morning my gf was on top of me and was dry humping over me. She had no clothes on while i was still in my pants. There is a chance that there might have been a pre-cum. She had her first day of her last period on 9/12 of the same month. After like 12 hours, she says she's been experiencing slight abdominal pain, cramps on thighs and lightheadedness and white vaginal discharge. Is she pregnant?
