frog how old is yours again? I've lost track? I'm in a bit of a similar predicament actually (although totally different!) - I had polycystic ovaries and am not going on the pill again, and I'm not a fan of condoms really either. So I was going to just leave it up to chance as we needed fertility drugs last time so the infertile person in me genuinely doesn't think we'll get knocked up in any hurry (if ever again). I'm fully aware that people can be more fertile after number one though. The thing is, if we end up having number two sooner than we realise, it would be full on but I'd rather risk that than wait 2/3 years and then start ttc again.
Having said that, I don't want to get pregnant before I've enjoyed my mat leave summer, my holidays and two summer weddings! Plus I'm just not ready yet. I was thinking it's fine as we don't have a chance to dtd these days anyway but actually we will have more of a chance when S goes into her nursery and when we're on our Spain holiday etc.
So I guess for us and for you, it's either condoms or run the risk?! If I were you personally, I'd be even more likely to make sure we use condoms bearing in mind your situ with your DP, even if he isn't a fan of them (let's face it, who is). Hmm maybe we'd better get some especially as we've got our first date night tonight although we might be too shattered and just end up having a good night sleep haha
