@monkey88 big hugs hun! Ttc isn't easy and it can really put pressure on your relationship especially when you are trying to work inside a certain time frame. My DH often felt pressured or that dtd had become a chore when i told him we needed to dtd.
If you dtd every second day your dhs sperm will be fine. I think it's if you do it every day or more than once a day that it can be an issue.
I'd still jump hubby today if i were you, might as well give it a go!
