Uterus “growing pains”

FTM. I’m 14w3d and the last few days I’ve been so crampy and just feeling like crap. I had an appointment yesterday and my ultrasound went great / everything was fine. My doctor did swab me though for any sort of infection. Other than that has anyone gone through a crampy period of their second trimester and it eased up? This cannot be how the rest of pregnancy is going to go…
