PUPPS at 14 weeks. Advice PLEASE! 😭

I'm 14 weeks today and was just diagnosed with PUPPS (the itchy rash that you're not suppose to get until the third trimester and doesn't go away until the baby is born). Its all over my stomach, back, chest, butt, and starting to go down my legs and arms. Does anyone have any advice on how they got rid of it or managed it? Was anyone able to get rid of it before the baby was born? Can't imagine 6 more months of this stuff! I've ordered Grandpas pine tar soap and it should be here today.
