I get a little worried too, I have a 5 year old son and I worry that i will have trouble conceiving this time around. I was 21 when I got pregnant the first time and 22 when he was born, and now I am almost 28, not a far jump but it worries me none the less. We are only on cycle three so I'm trying not to stress about it more, but I will admit sometimes the thought sneaks into my head.
good luck, and hopefully you get a bfp soon!
