We have one lovely DD from fertility treatment, and we had made up our minds that we would try to have another. In fact, when we calculated my cycles, we were a bit disappointed that we probably won't be able to start until January. It was a difficult decision, because I didn't have a great pregnancy and then I had an awful labour and delivery. I've seen specialists about my large painful epi scar, who could do very little, but now I've stopped BFing things are getting a bit better (but still very uncomfortable). However, in fertility doctor terms, I'm getting on a bit (), so it's a good idea not to leave it too long.
However, DH is now saying that we probably shouldn't have treatment, as we're trying to find a house and it's really stressful (current place isn't big enough once hypothetical DC2 is 6 months and goes in with DD1 - although I realise that that's looking in the future a bit!). And every time I get a twinge from the scar, he gets really nervous that we'll have to go through the whole birth thing again, and also the whole not-able-to-have-sex-and-hysterically-upset-about-it-thing.
Sorry, I've ranted on a bit, but it's getting me down to do the we will/we won't thing. We might not be able to have another, but I'd really like to try.
