Posted on Sat, 4 Apr 2015
Question: I have been on the birth control, tri sprintec for almost a year now. I just started taking the antibiotic amoxicillin for my sinus infection and I was to take the antibiotic for 10 days. I am on my tenth day and the doctor said it would mess with my birth control. I had unprotected sex tonight and used the withdraw method. Do you think I could get pregnant?

Brief Answer:
Chances of pregnancy less than 10%.

Detailed Answer:
Hello,
Thanks for trusting us with your health concern.
While taking amoxycyllin the birth control pill becomes less effective. Withdrawal method reduces the chances of pregnancy to less than 10%. If you had sex during the fertile period then it is best to take an emergency contraceptive within 24 hours.
Please feel free to discuss further. I will be glad to answer the follow up queries that you have.
Wishing you good health.
Regards.
