So here's the deal. I had sex twice, no condom and my guy came in me both times. Both times were 3-4 days before my period estimated start date. Now I'm 2 days late and have no idea if that could mean I'm pregnant. I'm having cramps like usual before my period and I've taken a test (it was negative). Do you think there's a chance I could be pregnant? Or could it be stress delaying my period?
