I'm 17 and I had protected sex with my boyfriend around my ovulation, 4 days ago. He didn't come inside. I've been having a watery discharge which is quite uncomfortable and a lot, and I'm not too sure if it's normal or not because I'm never really paying attention, but it feels like a lot. Also, I've been having light cramping (like period cramps)and gas. Is there any chance I am pregnant?
