I've been on trinessa for 2 months now and today i just took my third placebo pill and have yet to get my period. I have this urge to urinate a lot, like I will go and then 2 minutes later I'll kinda push on my bladder and it'll feel like I didn't empty my bladder enough? Me and my boyfriend have unprotected sex, but I'm on the pill and I know there's still a possibility that I could get pregnant. But I'm wondering if my symptoms seem more like a uti or pregnancy? I have lower back pains, but that's about it. No nausea or food cravings. Just a little bit worried! Anyone let me know what they think.. Thank you!!
