My sister-in-law and brother have also battled infertility. They have a 4 yr old daughter conceived through IUI. She was really private about the whole thing back in the day. Now, they are trying to conceive baby number two, and the one time wonder of IUI isn't to be. They are doing IVF with ICSI and had their second retrieval today. 21 eggs.
It's interesting to be going through something like this simultaneously with a family member. Also, my SIL and I have had a rocky relationship in the past. And, she's had a hard time with infertility too. And, she tends to be competitive. So, I worry. I worry that this won't work out for them, and they'll be devastated. I worry about the impact of what will happen if it doesn't work out for them - but it does with me. I selfishly worry about having to share the limelight of my first pregnancy with my SIL.
But, at the same time, I HOPE it goes well for them. I hope we both end up with simultaneous happy endings. And, I promise to be supportive and the best SIL, sister, and Aunt I can be. I'm grateful to have someone to share this with - in my own family - who knows exactly where I am.
