How To Get Rid Of Itchy Rash On Stomach During Pregnancy?

Hi, I am 15 weeks pregnant and I inject 120mg of Clexane daily. I ve developed a very itch rash on both sides of my stomach. The last time I saw my consultant this was not the case I only had bruising during my last visit. Can you suggest anything I could take to ease the itch and help the rash go away with harming my baby?
