DVP??

I’ve been having persistent pain in my left calf from the back of my knee down since about yesterday. Pain has been more annoying and noticeable today. I’ve tried to walk stretch and massage my calf and nothing helps. I looked up symptoms of Deep Vain Thrombosis although my calf is not red or warm to the touch, I did read that DVP is most common in the left leg for pregnant women and that’s where my pain is. Do you think I should go to the ER and get it checked out or wait it out and see if the pain gets better ?
