Spend some time without a bra during the day or night, just to give your skin a break.
I would let yur ob know bks my sister inlaws sister had that and shes due may 9 but they hav to induce her that itchy rash turnd out to bee some sort of skin disease that can be contagious to the baby and is dangerous..
It sounds like your skin is stretching and have developed stretch marks.
Try taking an oatmeal bath, its very good for itching and dry skin
Something similar happened to me in my first pregnancy. Turned out I was allergic to my body wash. So I put aloe on it swithched my body wash and it went away. The pregnancy hormones can do alot to the chemical balance of our bodies. Try process of elimination it could be soap, a lotion or even something you ate. Good luck. If all else fails call the dr. Better safe then sorry.
