Will I bleed after having sex for the first time. like a pin prick of blood not that much.?

I'm not sure if I had sex or not, I like had very very little ( pin-prick) blood. It also burned like crazy. It felt like I was chapped. I put a cool washcloth there and after about 5-7 mins. Not really sure. The day after I was slightly sore. But not really sure about why all this is happening?
