Hi,
This is our 20th month of TTC 
and we haven't had any hint of a pregnancy in that time. We have a 3 year old DS together and have had lots of tests which show no problems, but it's just not happening. This is my 3rd month on Clomid, started on 50mg but doc prescribed 100mg this month to try and bring ovulation forward (didn't ov til day 21 last month) and it seemed to do the trick as ov-ed day 16 this month.
I'd told myself I'd try until the end of this year, which would make it 2 years of trying, and so have started trying to prepare myself for life as a one-child family, but was wondering whether anyone out there got pregnant after such a long wait? I imagine that the longer TTC has unsuccessfully gone on for, the less chance of it happening without assistance...?
I know I'm incredibly lucky to have DS already, and my heart goes out to people TTC for their first baby without luck, and sometimes I think that because I've been so lucky to have him already then I shouldn't expect a second baby anyway - but I'm still desperate for one.
