Hello, I'm a big time lurker and this is my very first post. Please be gentle
.
We have been TTC for 18 months, both 37, my first, his second (previous marriage).
I've used CBFM for 6 months, have regular 27 day cycle, although ovulate fairly late CD16-19. Day 21 test was 43?? GP says I ovulate and as DH has previously proved himself we should just have more sex!!! We do have lots honestly 
We have appt with fertility consultant on 17th September.
I drink 2 bottles of wine each week, DH smokes 10 a day. We have both started taking vits.
What are we doing wrong???????
If you were trying for a Very Long Time and then got your BFP is there anything you did differently???
Please provide me with some hope - I'm desperate.
