I am 31 years old and when I had my son I was 20. I have had 2 mirenas and used the Nuvaring for 3 months. In October I took my nuvaring out, had a period in November and my husband and I are actively TTC. I have a fear of not being able to get pregnant since I was on birth control for so long. I'm afraid my body doesn't know what to do.  Does anyone have a similar experience ?
