Skin & Body changes during pregnancy

What changes have u experienced ? I noticed i have darker armpits frm week 13, and my linea nigra also started to appear longer and darker than week 10. I have developed some bacne which i didnt have before pregnant. And my skin around neck and chest become dryer and rougher. I dont have the pregnancy glow after 1st tri, only belly "grow" !! Do u have that "pregnancy glow"?
