Title says it all really! I (and a fair few of my pals) am not one of those, 'Whoospy I fell on a willy and got pregnant by mistake, how embarrassing!' wimmin. When you have been waiting a few months, it does rather feel as if absolutely everyone else gets pregnant by looking at a naked picture of Tom Hardy - but I'm sure that can't be the case.
I've therefore been thinking: you know, perhaps it just does take a while - for evolutionary purposes perhaps, to prevent the planet being over-run. Perhaps it can take a year or so not because there's something wrong, but because them's the breaks.
So to inform and reassure, I'd be really interested to know how long it took you to conceive, your age when you did so, and whether there were any medical factors that you knew of (including, and speaking as a plump lass myself, weight!).
