Help a paranoid girl out???!?

So I started taking birthcontrol but the pills just didn't make me feel right they also gave me a horrible yeast that didn't go away until I stopped taking them. I finished the pills out until I got my period and all I know I was fertile after my period because I have ovulation pain and I have the cervical mucus me and my boyfriend did have sex but he used a condom and pulled out. I'm just terrified that I fell pregnant I know chances are that I am not but I just feel so anxious. What do you guys think?
