since having the mirena iud my periods completely stopped, but now i think i might be pregnant. is that possible. I have the IUD for 4 years or so. This is the second time of me after in after my 2nd child. Through the 2 times I've had the IUD my periods have completely stopped. I don't know what to think or feel abut my situation, being my IUD has been good to me, but this time I'm not so sure
