Ttc baby 1

My SO and I had sex during my fertile days the day before I ovulated. This is our first baby that we are trying to conceive and the tww is killing me. I'm worried the sperm didn't live long enough or something lol I know that sounds silly but I'm going crazy waiting. We didn't get to have sex after I ovulated because of my work schedule so I'm hoping maybe the one time was enough. I put my feet in the air for 20 minutes, I really hope it works this month. Anyone have success stories they want to share that can ease my insecurities?
