First pregnancy— round ligament

So this is my first pregnancy. 17w3d. I don’t know if this pain I’m having is round ligament pain or not 😭 I feel it more in the mornings, and when I’m laying down on the side it hurts. It gets better throughout the day, but idk if that’s what it is, or not!!

Also been experiencing more discharge. Clearish/white but doesn’t have a smell. Normal right?
