IVF isn't right for everyone. One of my daughters was extremely ill right through, and her babies were very premature - delivered at 30 weeks by emergency section - little sugar bag size babies who spent nine weeks in SCBU. The impact of injected hormones on my daughter's body was severe, and she was told her health would only return when she gave birth. I flinch when I hear her say she would love to have another child, because I remember how ill she was. It's hard going being mum and grandmother in such circumstances. Thankfully, they all came out if it in one piece, but it could have been so different.
The CARE fertility website was very useful, and she met other pregnant mums in our region who have become friends. It's also a forum containing some very sad stories of failure and loss. Anyone going through IVF is taking on a big challenge even if it goes relatively smoothly. There's a high level of premature birth, particularly with multiples, and more complications. You just have to keep thinking about the possible positive outcome, be realistic, and get on with it.
