Sadly other then lotions to keep your skin nourished I don't think anything can be done BUT it's worth mentioning to your PCP or OB the next time you see either of them. Try Bio-Oil. I used many different creams with my previous pregnancies, but this time am using Bio-Oil & swear by it.
Congrats on the pregnancy & good luck

the only thing is creams, lotions or oils. your skin is stretching so nothing can be done sadly. try keep it moisturised
