1st IVF ended in miscarriage

mi
We were on 1st round of <a href="https://glowing.com/glow-fertility-program">IVF</a>, I have PCOS and hypothyroidism. Everything was great after the transfer, we got a high beta level on 11 dpt. After a few days, I got cramping and bleeding. It was around 5 weeks, I went to doc office to test again and my hcg level was declining. It was so heartbreaking. Our happiness didn't even last for a week. We still have several embryos frozen, but we don't want to go through another miscarriage. I am still depressed every time I think about it. 😞
