Good luck to BB's hubbie.
lol and BB - I think you guys and me are all in a similar boat (except BB is younger). I went to the GP this morning to ask about clomide. She says she has never prescribed it herself and is not sure she would feel happy doing so. She said at the very least she would want me to have a scan to check for cysts etc. but would probably prefer refering me to a specialist, especially as I have endometriosis. She wants to think about it and discuss with colleagues. I said if it was gonna be a few months of waiting to see a specialist then I wouldn't bother with it. She totally understood why i wanted to give this whole TTC thing a final push and I totally understand if she doesn't feel comfortable prescribing it without a specialist involved.
I see a lot of myself in what you are both saying. BB I keep thinking how did I get pregnant twice at 43 and not at all at 44 (but then neither of those pregnancies were viable anyway - so that's a bit of a daft thing to think
). You asked how it can make such a difference after only a couple of years and I guess the answer is that our fertility has to start fallling off at some point and maybe you were lucky with your last little one.
lol - I found it interesting that you said maybe you should be concentrating on coming to terms with not getting pregnant again rather than spending money trying to make it happen. I do agree, but obviously it is your decision to make. Many women DO have babies in their 40's but not ALL women who want babies in their 40's get them.
I told the doctor today that every time I have a period my endo is getting worse and I have no clue what is going on inside my pelvis. I could keep trying and never get another baby but end up in real pain. She agreed that I need to put a finite date to TTC and I have said if she doesn't want to give me clomide I will try for another couple of months and then get a coil put back in. It will be incredibly hard to do that and I know I will cry for the baby I never got but I have to look at it objectively. Having said that I will still try very hard for the next couple of months 
lol I hope you make a decision about what to do and I hope you and your other half are happy. And that all the other stuff gets sorted too.
BB You are a lot younger than me and those 4 years make a huge difference at the moment. However, if you don't manage to achieve another pregnancy then please please feel very proud of the pregnancies that you have achieved and the lovely little-uns that you've made.
So endeth the sermon
