Itchyness 17 weeks pregnant

Can any of you ladies help, I've been having this itch on my fingers n feet n toes idk where it came from im not allergic to anything so it's weird that i have this itch. You guys can't really tell but they're like little bubbles n i can sometimes pop them n they have like "water like" fluid coming out i never ever experienced this before. As u can tell my finger is swollen n it hurts a little when i try to put it straight. Anything helps thanks!!
