Hello, thanks for using health care magic.
With the effective use of birth control pills, the chances of getting an unwanted pregnancy
is very minimal especially after a long duration of use. More so, the use of emergency contraceptive
pills which has a failure rate of less than 0.5%, its less likely that you could become pregnant.
For sure, several drugs interact with birth control pills and decrease their efficacy but for sure amoxicillin
is not amongst them. Old data suggested that ampicilline which belongs to same class as amoxicilline was capable of decreasing the effectiveness of oral contraceptive pills; however, newer studies have contradicted this idea.
So, with effective use of your daily pills and emmergency pill, it is less likely that you become pregnant. If you are however still woried, you could do a home pregnancy testing in a month's time to be sure.
Best regards and hope this helps you.
