I didn't. I was more than happy to never ever have kids. Nothing about it appealed to me. Then I met DH and he wanted kids. I agreed, but always knew it was to make him happy because I knew how much he wanted a family. If he had for one minute turned around and said he didn't want to have any, I would have agreed in a flash! Even while we were trying for years, I was angry at my body for not being able to conceive - more of a "why can't my body do something it's meant to do!" competition with myself than a real desire to get the actual baby at the end. Even during our first IVF attempt....I still would have dropped it all like a hot potato if DH had decided we wouldn't go through with it.
But then there was an exact point where I decided I absolutely wanted a baby and wanted to be a mum. The first time I felt 100% committed - it was the very moment I watched our little embryo transfer into me on the ultrasound on our second IVF attempt. Now I'm just over 6 weeks pregnant and praying like crazy every day that we get to take this baby home.
