To test or not to test???

Stocking up on these guys! My husband is 30 and I'm 22. We've been married for 2 years and have been TTC since January. I've been logging every day, taking prenatal vitamins, working out 3 times a week and trying to get as healthy as I can to carry a baby! We want this so bad and the waiting game is driving me insane!! AF is due on Friday. I've been cramping, having back pain, mood swings but they're also typical period symptoms. So my question is, should I test tonight or tomorrow morning or just wait until my missed period? I'm so anxious to know either way! It's all I'm thinking about. 😪 what do y'all think ladies?!
