Staying calm through ovulation

My husband and I are currently TTC. Every month around my ovulation period I freak out. I try to plan the perfect time to baby make so maybe it will stick this time. Then I think we're doing it too much or too little or at the wrong time of day or so many other things. I overthink the entire process every time and then when it doesn't work I figure its because I stress too much about it. Don't get me wrong, we have plenty of fun doing the dance and getting plenty of practice. I just can't help but psych myself out sometimes...
