Dry skin/Eczema during pregnancy

Bailey
Is it just me or does anyone else have extremely dry itchy skin? It's gotten so bad I cannot fall asleep because every inch of my body itches. I have started to develop eczema patches up my thighs and on my arms. I have tried everything: heavy lotions, oils, petroleum jelly. Nothing works. 
Any suggestions or do I need to call my OBGYN?
