How long did it take to conceive baby #2?

We want to wait until June to start trying for baby #2, it would make our daughter 2.5 by the time baby #2 arrives if we got pregnant that month but now i'm second guessing myself because what if it takes longer to conceive second time around?! I've heard some get pregnant 1st the whiles others it takes months! it took 3 months with our 1st and we were actively trying with OPKs and tracking!
