Comment: Some things I tried and may have helped

If you have low back problems look to chiropractic (I would look for one that does the Gonstead technique).
As soon as we gave up on the worry and trying it happened for us.
I took Chaste tree (herb), and it may or may not have helped--- and it may or may not have given me twins.
And third ask friends and family to pray. I may have had too many people praying bc I ended up with twins! ;)
Third, remember you can be happy no matter how it turns out. This was something I came to right b4 I got pregnant.
Life is a beautiful thing, even without having your own biological children. And adoption is being a mother--- equally to having them form in your belly.
Good luck on your journey. I wish you all the best.
