I enjoy this one a lot. It's not too new agey or too spiritual for my tastes, and it's very relaxing. I fall asleep almost every time I listen to it. I didn't realize I fell asleep the other day, but I woke up so refreshed and when I looked at the clock I realized I was missing a chunk of time. The same woman has several different meditations available on Amazon, so you might want to check those out too.
I saw someone on here recently say she was using one from the Circle and Bloom website. It has meditations for each part of your cycle and for different infertility treatments. It looks interesting, but it's more expensive. Good luck!
