Possibility of getting pregnant

Hi, may I ask if there's a chance for me to get pregnant? Me and my bf had a protected sex on the 1st week of Nov and after 2 weeks, I got my period luckily it was not delayed but I only had it for 3 days. This december, i also got my period for 6 days with 3 days of heavy flow and 3 days of spotting. I searched for the symptoms of pregnancy and I experienced some of them such as dizziness, acne, gained weight, and etc. Now, it's been a week since my lower abdomen and upper abdomen hurts and it feels like there are butterflies in my stomach. Is there a possibility? Pls help, I'm worried.
