I have PCOS so I have no idea what CD I'm on but I literally haven't had a period in almost a year. However, I'm having the worst cramps right now. I was really nauseated earlier and I just have zero energy whatsoever. In the past two weeks I've thrown up probably 5 or 6 times. I've never been one to have cramps with my periods, usually just weepy and want to eat all the food in sight. I'm really not sure what's going on. We're TTC but all I'm having are BFN after a false faint positive about two weeks ago. Any advice? Should I be concerned?
