Am I pregnant?!?

Alysia • I`m just a simple girl
So my boyfriend and I had unprotected sex, it was our first time and we waited a long time. I noticed he produced a lot of pre cum but I didn't care until now. I thought I was getting pms, I got some cramps and my period came 3/4 days early. It was very light to a pink. It got slightly heavy but not enough to get on my liner, it's light. Am I pregnant ?
