Caffeine cramps?

Okay ladies, I realize this probably has absolutely so  correlation but today I splurged and got a large boba tea because well… pregnancy cravings. I’ve had barely any caffeine since I found out I was pregnant (i’m 7 weeks, 3 days) and now since drinking the tea i’ve been cramping realllly bad. I’m honestly not sure the kind of tea that was used which is my fault but now i’m freaking out thinking i’m gonna miscarry or something. Someone put my silly mind at ease please 😅
