Is there a possibility of pregnancy?

I am on regular birth control for almost a year now (sprintec) and am religious, I have only missed 3 pills and took them immediately (this was the beginning of me taking the pills). About 4 weeks ago I was prescribed Amoxicillan for a head cold the a week and a half before I started my period. I continued taking my bc at the same time and started my period 3 days early and (Thursday) and continued my period until the following Friday (my normal period is 7 days so this is not unusual). I had unprotected sex on Friday night. I started my bc back up on Saturday and was nervous so I took the morning after pill on Sunday. I continued taking my bc regularly and should start my period this coming Monday. I think it is just my anxiety but j have been very nervous about this upcoming period not coming (either due to the morning after pill or other causes) can someone give me a peacee of mind? Thanks!

Hello unknown6764,

Welcome to the EmpowHER community. Thank you for coming to us with your concern about possibly being pregnant.

Even with study data, the association between antibiotic use and combined oral contraceptive ) failure is still controversial.However, according to the latest available studies, experts and women’s health providers, only one antibiotic - rifampin (Rifadin) - has been proven to make birth control less effective.

Some physicians still recommend that you use an added method of birth control, such as a condom, to your oral contraceptive method during and for one week after antibiotic.treatment.

Unknown6764, you overdosed on hormones by taking an emergency contraceptive, which contain a high dose of the same hormone found in most birth control pills, and starting your active birth control pills.

An emergency contraceptive prevents pregnancy by preventing ovulation. That is how oral contraceptives also work.

For peace of mind, contact your gynecologist and follow his/her recommendations.
