I've had the mirena since October. I used it as emergency contraception, not realizing it was not approved. This was right after the last period I've had (nearly 11 weeks ago). I spotted for a few weeks afterwards, but no period, te spotting stopped a little over 6 weeks ago. I've been nauseated, swollen, bloated, insmonia riddled, and have been having terrible lower back pains. I am afraid that not only could I be pregnant, but that it could be something more serious like an ectopic pregnancy or an ovarian cyst. I also do not have health insurance until after the first. Thanks. Any advice appreciated.
