Painful stretching feeling in skin -19 weeks pregnant

I’m currently 19w2d and for the past 3 or 4 days I’ve had this painful tearing feeling on the top of my belly like my skin is ripping almost. Anyone else experiencing this? Anything I can do to help with the pain? Also, I’m nervous this means I’m going to see a lot of stretch marks and I’m only half way through this pregnancy. Thank you in advance!
