As the title says really. I have been TTC for a year or so, on and off, with no luck. We have a DS so not infertile and no problems showing up in medical tests, but every month when my period comes, I feel so down. Like I might as well give up TTC and accept that my son will be an only child. We wanted a small age gap and he's almost three already so every month the potential gap is getting bigger. Just had huge argument with DH as he thinks I am being too negative about the whole thing, but I find the monthly disappointment so hard to cope with. Any tips? Or sympathy?
