Difficulty Concieving

Looking for a bit of a lift to be honest. 

It's been 9 months since I started trying for baby number one. My partner has already had a child (9 years ago) 

We have recently been to have some checks as my periods are all over the place and everything so far has come back normal for me although I have not actually managed to identify my ovulation dates so just plenty off BD! My partner however who we thought lt would be OK has come back with some poor results. Has anyone been through the same and now have their bundle of joy? What have you had to do differently to normal? Any stories or encouragements are more than welcome. 

Feeling like its just not meant to be for us.
