I’m 16 and my boyfriend and I are sexually active. It’s been 3 days since I started getting extreme lower middle cramps, fatigue and nausea— 4 days since he was over. I had a 28% chance of getting pregnant during that day because I was only starting my ovulation window.

• No protection was used.

• No penetration took place but there could have been a contamination.

• I don’t take birth control.

• I haven’t taken a pregnancy test.

Is there a possibility that I could be pregnant?
