I was on birth control forgot to take the pill one day, day after that had unprotected sex and I'm taking antibiotic " Nitrofurantoin" so I was panicking and took the pill " take action " am I still in risk of getting pregnant?

I was on birth control forgot to take the pill one day, day after that had unprotected sex and I'm taking antibiotic " Nitrofurantoin" so I was panicking and took the pill " take action " am I still in risk of getting pregnant?

Low Risk: If you miss one birth-control pill, the best thing to do is to take it as soon as you remember, then take the next one at the regular time. If you don't remember until your next pill is due, take two at once. If you do this, your risk of pregnancy is very low. What you did will also keep your risk low but you may have some spotting. Best wishes! ...Read more
