Cramping 9w PP

2-3 times in the past two weeks I’ve had cramps so bad it’s hard to move...usually happens right after waking up. I take Ibuprofen and it goes away within 30 min and then usually doesn’t come back until a few days later...is this still normal uterus contracting back to it’s normal size or something I should mention to my OB? I have a history of UTIs but this pain comes and goes so just when I think the cramping is better it comes back! Anyone else still experiencing terrible cramping?
