Help, I have an allergic reaction to Palmer's Cocoa er Formula for Stretchmarks!?

I used this and now I have alot of itchy, tiny, red bumps all over my tummy..now I can't stop itching! I tried it in early pregnancy and it was itchy too but I thought it's because I'm stretching..now I'm 8 months and tried it one more time...man same results again. I tossed it out right away realizing this monsterous cream is making my life miserable. What can I do to allieviate this itching, I've washed it off but 2 days past and I'm still itching?!
