Chance of pregnancy

steph

Okay so last Friday I drank my pill at 11:30 pm the around 3:30 am I got diarrhea and had diarrhea for most of the day I’m Saturday. By the time I took my pill on Saturday at 11:30 pm I was fine and no more diarrhea occurred since then. Now I had sex yesterday... and he cummed in me once and we had unprotected sex. Should I be worried about pregnancy? This is my third month on the combination pill
