I don't understand?
Your doctor was mocking you or something when he said see you in a month?
He should have informed you right then and there if you could have sex or not and how long before you can. Not only that but I've NEVER heard of a nurse removing an IUD. I have a scheduled appt with a gyno to have mine removed on Monday.
If your bleeding or spotting, you should prolly go into a clinic, not to your doctor, he seems like an genuine ass. If that nurse took it out, she could have ripped or torn your cervix!
