Natural ways to help with infertility

Shelbie • TTC first for 6 years and miscarried at 7 1/2 weeks with twins. 3 months progesterone only. 5 timed intercourse cycles, 3 IUI cycles, 9 timed intercourse with trigger shot. All fails! Have till September to conceive on our own then we are onto IVF
What are some of the things you ladies have done to help with your infertility. Would love to hear, even if they haven't worked for you it might work for someone else, and it's always nice to hear of new things to try. Even fun things that you have done. Doesn't have to been all medical :-) We don't have insurance so going to a dr is out of the question. I have tried vitex, evening primrose oil, natural oils, chiropractor, healthy diet, progesterone, folic acid, mucinex. 
​Background: TTC for 2 years.
