I switched over from Mononessa to Nortrel almost a month ago. A couple days after I switched over, I had unprotected sex (I forgot I switched pills, we did it out of habit) I know that was dumb. But over 10 days ago I started my placebo pills and I STILL havent gotten my period. I’ve been nauseas, my boobs have been sore, I think that I’ve been peeing more, I’ve been tired, and I’ve been super bloated. I know the only way to know would be to take a test, but I want to hear opinions first.
