Help I think I'm going to delete the app

Me and my SO are trying so when my ovulation days are around I'll tell him hey it's 33% today and he used to get excited I'm not being anal about the whole thing well maybe a little cause I'm excited but I think the whole having sex on the peak days is stressing him out well and me when he doesn't seem interested and some time s me it's just seeming to be too stressful idk what to do?
