Baby #2

We have just started trying for baby #2. I can pretty much read my body well. My 1st pregnancy happened very quickly. I'm nervous that it won't happen as fast as last time. It's been about 2 ish yrs since my 1st and I had a c-section. I come from a very fertile family. Anybody else get nervous about conceiving again? Does having a c-section lower chances? I guess all we can do is keep trying!!!!
