Lost hope

I don't think I'll ever be able to conceive.. I've been trying since I was 14.. I'm 28 now.. I was married for 10 years.. Never had any luck.. Now I'm engaged with a wonderful man.. He has three girls.. We still haven't had any luck.. So I just don't believe it was meant to be for me to concieve a baby.. I wish the best to everyone who is trying.. Congrats to those who do..
