Hello everyone . I'm 30 weeks and 2 days

And for the past 3 days I have been experiencing period like cramping consistently throughout the day . The only thing that changes is they do increase at night and feel much worse when I lay down . I have tried HOT baths , I drink water like it's going out of style and have also taken lots of Tylenol but they will NOT go away . my question is , is this normal at this point in pregnancy ? Will they just go away ? Is this what preterm labor sounds like ? I feel like I'm TOO early still ... can anyone help me out . Is anyone else going through this ? What should I do?
