TTC after Mirena removal

Hey everyone! I have always tracked my periods even before TTC. The first time my husband and I started trying it took a month and we were Pregnant! I had never consistently been on BC before my first child. At 6 weeks PP I got the Mirena BC. I never had any issues and kept it in for about a year and a half. We had it removed in January and I have gone back to having a regular cycle and ovulating (by March) but have still not been able to conceive. Have any of yall had experience with TTC after Mirena? I'm trying not to get frustrated but it's hard when you are so ready to have another baby!! TIA for your help/advice!!
