Just curious really - DH and I have been TTC for 3 years in November (long story - fertility issue on his side which we knew about so we did expect this)
I know it's just the way it is, but every single person we know who has had a baby or is pregnant either had a surprise unplanned pregnancy or fell pregnant within a few months if trying.
Our latest friend to fall pregnant took 5 months which is the longest of anyone we know in RL.
It is a bit disheartening TBH especially because I think people are now starting to realise we are having problems as we have both always been openly broody, have a decent house and jobs, married for 2.5 years etc - from the outside it must seem like there is no reason for us to not have had a baby by now! 
I know it takes most couples a lot longer than a few months and we just must have a group of fertile friends!
So...how many months were you trying?....GO!
