I have been on Mirena for about a year and a half now, my boyfriend and I have been together for over four years now, I'm only 20, but since we have been together so long we only use the mirena as our contraception, the last two weeks, I have been having extreme mood swings, crying over the most random things, and have been nauseous almost every day, never throwing up though, I've also had tender breasts and slight bleeding, I haven't had a period since the first few months of having mirena, getting nervous if I'm pregnant, have even noticed my stomach feeling slightly firmer, not sure if its just me being nervous and just thinking I'm getting bigger, but I even feel funny in my stomach region, and advice?! not really sure what to do at this point! thank you!!!
