Can An E. Coli Infection Cause Irregular And Lighter Periods, And Will They Return To Normal After Completing A Course Of Ciprofloxacin?

Hi, My period has been irregular. It became lighter by almost two days (it used to be three days, now its barely two). I went to the hospital, and I did a couple of tests including a HVS. They told me I had e coli growth in the swab they took. I m curious to know if there s any link with this infection, to my irregular and lighter period and if my periods will return to normal when i finish the course of antibiotics i was given (Ciprofloxacin)
