Pregnant?

Jasmine

Iv been talking to this guy for about 2 months now and we’ve had sex about 5 times. Two of them being while I was on my period and we were Using a condom Ofcourse. When I talked to him he said they didn’t break and everything seemed fine. Iv been off of my period for about 5 days now and 2 days ago I started throwing up and today my back started hurting. I took a pregnancy test and it was negative, is there still a chance I could be pregnant?
