It's entirely possible that the migraine was stress related. As for the pelvic pain and bloating, could these be possible (even if augmented) PMS symptoms? If you've had a regular period while using Mirena it would be unlikely that this pain would develop suddenly but if you haven't had a period in several months it's likely that this could be the problem. As for the numbness, if I were you I would make an immediate trip to the doc and if your regular doc can't get you in, go somewhere else. Numbness/tingling in the face and arms can be a side effect of stress but generally only if you are experiencing some panic attacks as well. That it is only on one side doesn't lend itself to stress. My advice... until you can get to the doc cut caffeine, take Tylenol and try to relax. Give your body every chance you can to recuperate. If the problem is the Mirena there's good news...it can be taken out!
