Confused dont know what to do

I had sex intercourse dec1st 2018 without condom but he pulled out and then igot my regular period. I then had sex intercourse again without condom on dec25th2018and he pulled out and i got my period early this month of january5th2019 and it was heavy and i had it for 8days-9days which its usually no more than 6-7days but idk if it was my normal period or not? I was sick and on meds for 2weeks cuz i had bronchitis, the flu, and Im scared to be pregnant because the guy i had sex with doesnt want kids because he has 2 already with his ex. What should i do? I havent had a chance to go get a pregnacy test yet but im scared to take it. I mentioned it to the guy and he said he didnt cum in me🤷‍♀️ what should i do? Do you think im pregnant?
