infertility

Hello,
I hope this post will not be discarted as there are a few others with the same issue, but after reading in depth , is not helping me....
I am , from the bottom of my hearth, looking to get a second child. The first child that I have, I was able to carry at full term, deliver at home quite quick according to the midwife; he is the love of my life, and it was concieved with donor eggs (at 36y).
I was diagnosed with thyroid issues 15 years ago, when I was doing fertility treatment. Only 3 months ago a homeopath told me that it never was a thyroid problem. I had it `cured` within 2 weeks with Pituitarium anteriorium.
The previous diagnosys was cysts before menstruation and would become smaller after the bleeding. I was told is normal. And was under laparoscopy for very extended endomethriosis on the left ovary, and less on the right, and some additional tissue in the uterus which I was told would not necessarily prevent implantation but is better to be removed.
No blocked tubes.
My cycle is between 26 to 27 days long. Heavy bleeding day 2 to 3, after that is normal, dark. Was extreme painful before having my first child. Now is not so much ( I also do some tapping around uterus before period and that helps with the pain).

Never took the pill even if it was reccomended when I was 22 y old due to extreme pains.
I had 4 IVFs , all the blatocysts were stopping from developing in the last stage ( between day 4 and 6) , hence we were advised for donor
We are wishing badly one more child and since homeopathy did so many wonders into my life so far , I am entrusting my biggest wish here as well. I have seen a handfull of homeopaths, obviously, so far but no results.
I am hoping, to have another point of view, myabe more successful one here.
Thank you!!!!
