Ava bracelet?

Hi all! My husband and I have been ttc for 6 months now. Really struggling with post birth control hormonal issues.

we are debating spending the money for the Ava bracelet but it’s quite expensive and we are unsure if it truly works.

Had anyone used this and had success/failures? Is it worth the money?

Any other suggestions, recommendations, ideas to boost fertility and have better chances? (We’ve been using this app and fertility strips as well).

Thank you SO much.
