Should I call my doctor?

Hey ladies, just looking for some opinions! This is my second baby I am currently 21 weeks and 3 days, my first pregnancy was absolutely horrible with preterm labour from 26 weeks on. I’ve had cramping all through this pregnancy but today started to experience some heavier cramping and sharp pains ( like a stabbing feeling) with lots of pressure. I had no spotting today but I recently had some slight spotting a few days ago. Should I call in to the hospital to get checked or am I just overthinking from previous experiences.
