The lifespan of sperm in the vagina

I know sperm can live 3-5 days in a women, this is also if she is on birth control. My question is how long can the sperm live in the first week of just starting birth control? When does the cervix become an unsuitable environment for sperm? If the pill is not taken correctly within the first 2 weeks of just starting birth control can this cause the environment to still be safe of sperm to live until an egg passes? (saying one incorrectly takes pills: if multiple pills are missed at a time)

Hello Anon,

Thanks for reaching out to EmpowHer today. You can still get pregnant in the first week of beginning birth control pills. It's usually recommended you use a backup birth control method for 7 days after the start. Some doctors recommend up to 14 days after the start to give the pills time to take effect. BCP are highly effective in preventing pregnancy if taken correctly, so it's important to get into a good routine with them.
