I had mixed feelings this cycle, but the TTC feelings definitely "won"!!!! It was hard early on to get into the BD groove, not just because of mixed feelings but because I still had a lot of sadness and overwhelmed-ness, which is not particularly sexy. I powered through it (DH's eagerness helped) and by the time I finally O'd (CD 18), I was rarin' to go.

For me at least, DTD a lot helped my mood and energy level, so I think it was good whether or not it resulted in a BFP.
It's okay to wait for emotional reasons, or just half-heartedly try because you aren't sure. Just go with your instincts. It's very normal to feel conflicted about how much you want a pg right now...
