Going through IVF, feeling defeated with no knowledge and support. What helped you?

Hi wonderful ladies!
I have been going through a lot as most of you would have struggled with. PCOS, failure to conceive naturally for years. Now on IVF journey for last two years. Had a miscarriage in first cycle and now starting next.

I feel so depressed that there is no ecosystem existing to support which is beyond these doctor visits. Please help me with your experience.

1. Did you take any supplements to increase the chances? Whether that is prescription or just something you know already
2. Any brands available for me to buy right now?
3. As I will be a first time mother, are there any resources available for me to be educated and informed about the journey and make right decisions with what do I need to do when, what should I eat when?
