I have been taking Trinessa for over a year now and it has been great. I have never had any issues? I had sex with my boyfriend 3 weeks ago without a condom but he pulled out. Today is the first day of the green pills and I have not gotten my period yet. I had also been taking antibiotics for a sinus infection so maybe that's causing this? I feel silly for worrying but I am completely freaking out. Does anyone have any ideas/ suggestions for me?
