P.S. Forgot to say how nice it s to hear from Fireflies. I'm glad your wee baby is doing well. Sounds like he's a good eater(drinker, feeder?). These early times of constant feeding won't last forever, so snuggle up and enjoy as much as you can.
As for how long to wait before ttc again, it depends on a few things. My sister had C sections, and had two babies (accidentally), 13 months apart. I think the scar held up well. It was her mental health that fell apart, but that's a whole other story and had nothing to do with her gorgeous babies.
Also, some women don't have their fertility return for a while if they are breast-feeding, so that may be a factor. With my babies, I didn't ovulate for ages - with my last baby I was waiting for about 18 months - nearly drove me mad as I wanted to ttc when he was about 10 months old, but couldn't wean him. I tried vitex, but it didn't work, I just had to wait.
As for using your frozen emby, I think I'd give myself a time limit ttc naturally, then go for the assisted. Sometimes having a baby will boost fertility.
Tina, it's great news that you are getting close to finding a donor and starting your treatment. Very exciting.
