Sleepless baby .. 12 weeks

I don’t know how im functioning .. my baby still wakes up constantly every hour of the night . She’s fed .. diaper changed .. I give her the pacifier and she will go back to sleep for an hour . She’s 3 months and still to early to sleep train but I have no idea what else to do at this point . According to everyone else in this group this can’t be normal . Yes I’ve tried everything out there .. white noise swaddle dark room , pretty much everything .
