Cran-Pineapple Juice 😩

Okay so y’all, this is one of my absolute favorite juices right! I hadn’t had it in weekkkkkks! Like since I was 3 weeks pregnant (10 weeks now) so my hubby got me some while out yesterday. I drank a glass before bed, & woke up with slight cramps, thought I had to pee, so I went & laid back down. They faded. I then woke up perfectly fine, drank some more juice & within 10-15 mins I was cramping yet again. I told my husband I’m not drinking anymore juice, took two Tylenol with water, & have been fine every since. 😩 & it’s been hourssssss of course. Is pineapple like a no no or something? Am I missing something? 🥴 I know it’s not the cranberry because I’ve had like 20 little bottles of straight cranberry within the last week 😂
