IM SO CONFUSED

So I called my doctor today to say I got the smiley face on the OPK but I don’t go in for my <a href="https://glowing.com/glow-fertility-program">IUI</a> until tomorrow morning .. I don’t understand why I need to wait a day. Everytime it’s been the following day and this is our 4th attempt. My wife is worried it’s not going to take again. And according to Glow I ovulate tomorrow but my chances of pregnancy go down 10%!!

Ugh I’m so sick of the hurry up and wait game. I just want to have a happy healthy baby
