I know how you all feel - it's just shit. Yesterday at work I was listening to two colleagues talk about when they'll have their second and be off on mat leave, and another talk about when she'll decide to have her first. I felt like shouting there's no guarantee, you can try and try for fucking years but still end up with nothing.
As for families, it looks like neither my parents nor DH's parents will get a GC. DB and SIL don't want kids, and BIL would have to stop spending his days smoking pot to decide to parent. I know that DM is devastated FOR us, and DF probably is too but we have never talked about it. MIL on the other hand has been asking for GC since we got married. We have a policy of telling her nothing - she has no idea of the IVF or the miscarriages as a result, and instead blames me for the lack of GC as I'm such a 'career woman' (aka heartless unmaternal bitch). Last time she said that I almost yelled that my career has enabled us to pay for the IVF but turned to the gin instead 
Sorry for getting so long - I'm just really feeling it at the moment. Wedding anniversary this week and talking about updating wills, but then realising that we have no one to leave anything to has rather depressed me.
@EmsIMO We have had IVF due to MFI - never been pregnant naturally. Two MMC now, and the clinic thinks its immune issues. I'm at the same clinic as @KittyKatSmile so I have hope!
I took my second dose of humira (weird injecting something that costs over £500 a pop!) and then need a follow up NK cells test next week to see if it's worked. I've no idea what will be the next step if it hasn't.
Has anyone had a drastic change in their cycle after a miscarriage? I was (before the first miscarriage) around 31-32 days: after the first MMC it shortened to 30 days, so not a big deal. I had my second MMC at the end of April, and since then it's been at least a 40 day cycle - today it's 41 days and still waiting. Makes it impossible to calculate, which I really need to be able to do so I can clear my work diary for the possible FET.
