Hello, my name is Josie. I had the mirena inserted probably 5 months ago. I am having stomach pain/cramps, side pain, a shooting pain where I would normally get cramps, back pain, frequent urination, and nausea. My last period was maybe 2 weeks ago and lasted less than a day which is very unusual. I went to the emergency room because I thought i was going to urinate myself and they did a test...They found no infection or sign of pregnancy. I then went to my Dr. who performed the same tests and said the same thing. He prescribed me cimetidine 800mg for my stomach pain/nausea. I have also gained about 8 pounds since my last Dr. visit but they said nothing. My stomach looks bigger. The past couple of days I haven't wanted to eat. What is wrong with me?
