Terrified that I could be pregnant!

[plushiesaremyjam]

I took birth control for almost a month and the packaging said that I didnt need any other form of birth control since I started it the first day of my period. So my boyfriend and I had sex 3 times. the first time was with a condom but the other times they were without a condom but he did pull out in time and i was on birth control that i had been on for about 2 weeks. What if I am pregnant? I got my period right after stopping my birth control (where we did not have sex after that) (also I stopped it because of bad side effects) and it seemed to be a very light period but that couldve been from the birth control but it was still a period that felt the same as any other period ive ever had....can anyone give me any insight?
