What Now?!!!!

My hubby and I have been TTC for like forever!! Usually the glow app is on point and as I’m sitting at my desk I’m like where is my pd. Where are you pd?! I log onto the app and realize I’m almost a week late which NEVER happens btw! This app is ALWAYS correct and now I’m just confused, I don’t know if I should wait a few more days or run home and take a pt... Help!!! I’m way too excited not to mention I’m on a crazy low calorie diet because I ballooned up to 290 because of stress and overeating which is also one of the reasons I was having a hard time conceiving. What Now?! Updateeeeeeee
