A few weeks ago, my boyfriend and I had PROTECTED sex. To make it even better, he didn t c*m. We also rubbed our genitals together, but again the didn t c*m. He was completely dry. There wasn t even any pre-c*m. (Sorry for being so vulgar?). Anyway. My period was supposed to start today. It has not yet. But I have all of my regular PMS symptoms: bloated, acne breakouts etc. My breasts are not sore at all. I don t have any weird cravings, I don t have any nausea . I m honestly 85% sure that I m not pregnant. But I think I m stressing myself out about it. My stomach has been cramping though. I have had slight uterine cramps like a typical period. But they go away. I ve had no spotting. I stay hydrated, I eat relatively healthy. A little bit ago I peed and it was a deep orange-ish color. I have a history of ovarian cysts , my mom has a thyroid disorder , if that helps anything. I m also seventeen. I ve read that periods can go from being regular to being irregular during adolescence . One more thing, I had a later period (like a week) back in October, but it did come. Am I just stressing myself out about this? What s going on? Anything would be nice. Thanks!
