First response has a fertility test you can buy cheap at walmart. Otherwise i got testing done at my obs office without insurance. It wasn't cheap though. But i was prescribed clomid which help you ovulate. The clomid without insurance cost me 30dollars every month. I did 6rounds.
Maybe you should talk to your OB about this pill it's a "fertility" pull but what it does is make sure you ovulate every cycle since we don't always ovulate every month. It's the first step towards the fertility treatments but he said its pretty effective for women who aren't infertile and jst can't seem to conceive due to missing that window of opportunity :)
