However, I have skipped the placebo week of pills since that time, so that I would not have a period each month. It's been going fine up until last week when I got strep throat. The doctor gave me a shot of penicillin and a steriod shot, along with a prescription of Amoxicillan. About 5 days after the shots and being on the oral antibiotic, I have begun spotting.

Is this normal? Is it due to the antibiotic lessening the effectiveness of the birth control?

I have since completed the antiobiotics, and have a week and a half until the "placebo" week in my pack. Is the spotting going to stop?

Any advice is appreciated. Thanks!
