You poor thing! There are options though, please don't despair. As a PP has said, not having children can still lead to an amazing life - but if you do want to be parents, there are lots of options nowadays.
First, you need to find out what is the problem. If your partner is infertile, you can get donor sperm and it could be quite simple (although obv there may be psychological issues for him). If it's you then there are all sorts of options depending on the situation. The consultants will talk you through all the possible problems and solutions.
DH and I met when I was mid 30s and by the time we married and TTC it turned out I was perimenopausal. We tried IVF but I had no eggs, so eventually went abroad for donor eggs. Ten years later I have two gorgeous children and couldn't be happier - the fact that they are not genetically mine is totally not an issue (although I accept they may have some curiosity when they are older).
We also looked into adoption and fostering. Women who can't carry a child can also look at surrogates. I realise some options aren't cheap, but please, don't do anything rash - there are so many options these days.
I hope you will feel more positive when the hangover has cleared - talk to your DP, register with your local fertility clinic if you haven't already, and fingers crossed!!
