possibly pregnant 🤰

Okay soooo I have been using the glow app to start tracking my periods and knowing my ovulation cycle, not currently trying to get pregnant yet. Last month the app said my chances were 3% so we figured it was a "safe" day. However, my period is only 2-3 days late which is not really normal for me. I am usually always at my 28 days or a day before. If I am pregnant, me and my husband will be insanely happy but do you think I'm just over thinking this and am just normally late this month 🤷🏻‍♀️ I feel like if I am just late I'm leading myself to being disappointed .. every time I go to the bathroom I hope to see nothing there 🤞🏼I am going to purchase a pregnancy test tomm but just don't want to jump the gun... any thoughts??
