I Just Went To My Gynecologist Today To Take A

I just went to my gynecologist today to take a urine sample for a uti. I currently take Camila Birth Control and my doctor prescribed me the antibiotic Nitrofurantoin 100 MG twice a day for 7 days. The only thing she told me was to pee after sex. I tried to contact the office but they were closed, and I was wondering what this antibiotic will do to my birth control and if it will make it severely less effective.
