I was on zinnat for 5 days and got additional antibiotics augmentim for 5 more days i also forgot to drink my bc for 3 days and had sex around my ovulation???
Of course there is a big chance!! First of all, you have missed more than 2 tablets of birth control PLUS antibiotics reduce the effectiveness of your birth control pill so that is a big double whammy! When you are taking antibiotics and birth control pills and dont want to become pregnant, you want to continue taking your Pill but you also want to use barrier back up, like condoms, the ENTIRE time that you take antibiotics AND for at least seven days after you finish them! You dont normally ovulate while you are on the Pill but by using antibiotics and missing pills, the possibility is there that you could ovulate but there is no way to know when and if. If you are using an app to figure your "fertile" dates then STOP using it. It doesnt apply when you are on the Pill and even if you are not, those apps are based on averages so they are just "guesstimates" not gospel truth! It is just going to give you worthless information. You need to use condoms if you have sex for the next two weeks! After that, if you are not on anymore antibiotics and havent missed taking any pills then you should be "safe" again.
