Anyone know what this is?

I only put this under this topic because I’ve never had this problem until this pregnancy. It comes and goes but this is the biggest it’s been. Most of the time it’s just itchy. I’ve put eczema lotion on it and it only stops the itching. I’ve had it for most of my pregnancy. I’m 19w and 3D today
