hairy glad you are feeling a bit better.
When I was in your position I hated hearing how people's luck turned around ("I don't give a shit how good things ended up for them, what about ME?" I used to think) but as you seem to be much nicer than me and taking heart from other people's stories, I'll tell you mine (feel free to ignore):
First tried for a baby with H no 1 - joint decision, him very keen. Tried for over a year. During this time thought he was getting distant, he said there was nothing wrong. Got PG, age 28. Told him, he burst into tears and told me he didn't want to be married any more. I had a miscarriage a week later - was utterly heartbroken. We broke up, I thought well that's it for me, I will never be a mother.
Met DH a couple of years later and married when I was 33. Got PG when I was 34 and about to start PGCE course. Waited till the last minute to pull out of PGCE in case I had a miscarriage. Pulled out. Two weeks after course began started bleeding. Missed m/c - pregnancy probably died about the time I cancelled the course. Once again heartbroken.
Did not get PG for another year. Felt completely frantic. When I did get PG I didn't get my hopes up. Miscarried quite quickly. Utterly devastated.
BUT then got PG with DS1 the month after. Age 35.
Got PG with DD when DS1 was 9 months old, not trying, just no precautions. Had her age 37
While we were waiting for DH's snip appointment we had an ahem drunken careless encounter and DS2 was on the way. He was born when I was 43.
My Mum tells me that BOTH her grandmothers had babies at 48.
I still can't believe that I can have had all that trouble (so it felt) conceiving, and three miscarriages in my twenties/early thirties and end up with a surprise late baby by accident.
Do NOT give up!
