Stretch marks and pupps

I made it all the way to 7 and a half months...now at 30 wks of my first pregnancy i have stretch marks and pupps...my stomach is so itchy i keep its greased up but thats not helping..this sucks so bad i heard it can spread to other parts of the body and im really hoping that doesnt happen...i also read that pupps is common in women pregnant with multiples and boys and what do u know im having twin boys this must have been meant to be 😟😟😟
