Brummie you're right, your friend who tried 2 years doesn't know how you feel but there are a lot of similarities between not being able to get pregnant at all and having miscarriages, so she probably thinks she does. In both situations you are facing people asking you why you haven't got a child when actually you may have been trying desperately for years and years. In both situations you may have an insane jealousy of pregnant women and those with babies. With infertility there is a grief for the child that you don't have and the life that you thought you would be living by now and still aren't. It's like when people compare divorce to a bereavement, you are mourning the life you thought you were going to have. Lots of you talk about age gaps. In my case, it's the age gap between the child I would have had if I'd got pregnant when we started trying and the child of my best friend who is now approaching 4. Our social group have pretty much all got babies now, by the time we have one (if it happens at all) they will all have toddlers or kids in school, so that shared experience and our kids playing together that you dream about will be gone.
That said I do agree that unless you've been through miscarriage yourself, and more than once, you have no idea of the horrifying, raw grief that it brings with it. The grief of infertility is very much there but it's not the same as having babies taken from you. Likewise, I wouldn't pretend that going through two miscarriages qualifies me to understand what it's like to suffer 4 or 5. Your friend does not know what you're going through, but she probably does have a better idea than someone who has never had any issues with pregnancy.
Sorry, that came out as a massive ramble. When the acupuncturist asked me if I had finished grieving, and I related this to the ladies on the infertility board I have been posting on for the last 2 or more years, they didn't really understand the difference between grieving over miscarriages and the continuous grieving that you are doing over infertility anyway. I was already grieving for the baby I didn't have before my first pregnancy and mc. I genuinely don't know, now that the raw grief of the miscarriages has subsided (ie I'm not crying every day and thinking about nothing else all the time), whether my continuing emotions are related specifically to the miscarriages or the general upset and frustration at still not having a baby or a viable pregnancy over 3 years after we started, while all of our friends appear to easily live the life they had planned (one couple went travelling round the world for a year before 'settling down to have children'. She gave birth 9 months after they got home [jealous].
And there you go. I just continued the ramble. Apologies!
Zita West comes highly recommended by anybody I know who has had experience of her. It's all out of my price bracket though so I haven't investigated it as yet.
bootles what a relief about your pay!
counting there has been a lot of research about the effects of positive thinking (the mind body fertility connection is an entire book about it). If I were you I would continue to believe in my mystery pills! 
boozle I cannot actually believe your head teacher said that, that's ridiculous! 
Girlie great work! I like doing the blunt, honest approach sometimes. I really wish it wasn't such a hidden subject.
bythesea ouch. Hope you're pain free pretty soon!
Brummie the negative test is a good thing but it still hurts to see it doesn't it. flowers hope you get yours soon.
tanny take care.
Thanks for all the luck ladies. I am feeling totally and utterly exhausted after the last 2 weeks and am now going to bury my head in the sand and keep as busy as possible for the next 2. See you on the other side! Hopefully all of us in the 2 week wait will be coming back with bfps that lead to successful pregnancies [happy].
