How long did it take to conceive your second?

DH and I just started trying to conceive our second. With our first, I got off BC, had my first period and then we started trying. Got preggers the first month. I thought it would be the same thing this time around, but it doesn't look or feel that way. AF is due the 30th but I have symptoms. I'm worried bc I heard the 2nd babies take a while? If that's the case, I wish we had started earlier. How long did it take to conceive your second?
