I'm sorry Leisylou
If you're not ready for IVF then don't do it, you may change your mind later and it may be too late and then again it may not be.
It's a really difficult process emotionally and I think you should be ready for it. Given your fertility I think you may have a chance with IVF (better than me), but be guided but what you want to do, not what you don't want. Maybe you can see a counsellor to help you decide?
But we're also here to help you through it. Also not child bearing need not be childless, as there are lots of ways to have kids in your life.
