I worry myself too much. Can you tell me what you think about this and if I'm worrying for no apparent reason. I took antibiotics for 7 day starting the 15 of dec and ending 21st. And continued to take my birth control pills. I had a week of my regular pills then inactive pills had my period then 5 more days of regular pills. Me and My boyfriend fooled around last Friday.. His manhood was in me 5-10 seconds. He did not wear protection. I am on birth control as explained above. I know there is a chance of pregnancy from Precum. Anybody have anything that will give me a piece of mind? I know the chances are extremely low but I worry myself to death.

No birth control is 100% effective, so yes, there's a chance of pregnancy.
