Mirena and reccommended

I have not been able to find the strings. Initially my doc had cut them to short where they were causing my husband pain during intercourse. She said they would soften up and it would get better. Last week when we finished, I had horrible cramping, almost like contractions. This only went on for 30 minutes but it was pretty bad. I called and made an appt for tomorrow. Hopefully they will just take it out. I have the lower belly bloating too! and gained nearly 15 pounds in the first month alone. I have factor V which is why my doc recommended Mirena, however I am now reading it isnt recommended for people with blood clotting issues. I really just want it out!
