I'm so sorry for all your losses, but welcome. I can't imagine what you've been though. I hope IVF is successful for you. I am planning my first IVF cycle also so I don't have a lot of advice to offer. But, the women on this board and very supportive and extremely knowledgable and I know some have done PGS or ICIS or are planning to, so I'm sure you'll get some good info.
You may also want to check out the Trying to Concieve after a Loss board - they all understand what it's like to have dealt with one or more losses. There are a few of us who hang out on both boards!
