You're not really the odd one out Andi.
H and i had been married 2 years and 5 months before i got pregnant. If time was on our side we would of waited another 2 years so we had been married 4 years before trying. We really wanted time to ourselves, to adjust to marriage and move into a bigger place without it being a struggle.
However we decided that we didn't want to wait until we were in our 30's to try for our first just in case we had major problems.
