So I've been regularly taking the birth control pill Trisprintec for the past 9 months on time and everything. In October I got a UTI and was put on antibiotics for 3 days (October 5-7). I was told that my bc would become inactive for about two weeks after the medication. After a week of the pill being inactive I had intercourse for about literally a second without a condom then decided I wouldn't since my pills were inactive. Anyways October 30th comes and I get my period like every 3rd day of the week of my inactive pills. My period lasts 5 days and it was very normal but slightly lighter than usual the last two days. One week after my period I spotted very lightly once a day for two days. It is now November 27th and I should be getting my period tonight but I haven't yet. Usually I start feeling cramping by now. I'm not sure if maybe it will start tomorrow (it used to start a day later up until July). I've felt normal since my last period. I'm not sure if the antibiotics could be delaying my period or if I'm pregnant. Every other time I've had sex I've used a condom.help!!
