I am using birth control pills and had unprotected sex. We used the pull out method but I am still worried about pregnancy. I have not been taking the pills at the same time everyday but they are within an hour of the normal time. What are my chances of becoming pregnant if precum was present? I also take antibiotics frequently.
It prevents pregnancy by 3 ways...
1. Makes the mucus of the cervix block out any sperm.
2. Prevents ovulation from even occurring.
3. Makes the Endometrium inside the uterus implantable to a fertilized egg.
