Ok ladies forgive me I'm a little ignorant at this after all I am a man. My wife and I tried to conceive for years and had no luck. Last year she had surgery and the doctors said no conceiving for a year. She had an IUD put in and it comes out in a month or two. With that said we decided to start checking CM however we are having a hard time seeing the difference. Question we had was will the IUD throw this off and not allow changes in the CM?  If so how long after it comes out should we expect changes? We asked her doctor but it would appear the small town doctor that put it in doesn't know much more. Please help ladies!
