I have had UTIs for the past couple of months now. The doctor prescribed me Cipro for the infection. I am also on the birth control pill. Both this month and last month, my period has started early (about a week before the inactive pills). They are also longer than usual (last month was around 7 days; this month is at 7 days). My period also has more blood clots than usual. My period isn't heavier than usual and I do have heavier then lighter days. I can't remember last month, but this month, about 4 days after I started taking the antibiotics my period started. Should I be worried? Are antibiotics and my unusual period related?
