TTC #2

My husband and I are trying for baby #2. I just had my Mirena removal in March. AF came mid April and was the heaviest (aka worst) it had EVER been. Now I'm on day 37 of my cycle and wondering what will happen next. I've taken a few tests and all have been negative. :( my husband doesn't want to invest in opks or anything like that and just wants to "let it happen" but I want it now!!
