So on Wednesday night I had unprotected sex and he finished inside me, I've been on birth control for about 3 years and take my pill at a regular time so I thought it was fine but Thursday morning I woke up with strep. Yesterday I got antibiotics but I haven't taken them because they will make my birth control ineffective and I'm scared because I've heard sperm can last up to five days in the body. I really don't want to get pregnant but I also really want to take my antibiotics to not be sick anymore. Any ideas on what to do?
