why is this so hard..

I’ve been TTC with my SO for 5/6 months now and it’s SO frustrating with him sometimes. Whenever we’re in my fertile week it’s like he doesn’t want to do it as much. Whenever I’m not in my fertile week he wants to do it like crazy and tells me so badly how he wants us to have a baby this month or soon, etc. My heart is BREAKING because it’s like he’s taunting me?? I know he’s not but it’s sooo frustrating and I’ve explained so many times to him how we need to do it in a certain time frame but it’s like it doesn’t click.
