Ladies (and that is not a sexist greeting. This forum better be women only ;-)---thank you for your contributions!! My oh my. I had a Mirena put in shortly after the birth of my daughter. No pain from insertion, but afterwards, dizzy, nausea, headaches...and CRAZY. I would fly off the handle. We weren't sure if it was postpartum or the Mirena. So, out it came and I straightened out within 24 hours! Now, you may think I'm stupid, BUT I cannot do traditional pills because of the breast cancer history. I spoke with my new physician (switched insurance plans--new doctor) and we decided to try the Mirena one more time (now that I couldn't possibly be post partum). Insurance pays for it, so we will try it. Well, guess what. It has been three weeks. This time around, the doctor PAINFULLY inserted the device. In three weeks, I've been dizzy, nauseated and CRAZY again. Oh--non stop bleeding. So, I'm getting it out as soon as they can give me my appt time. I don't know if this reaction is to a foreign device in my body OR to the chemical. Either way...we have to do what we have to do. Prayers to all of you and do not hesitate to take care of YOU. God bless!
