I'm about 5.5 weeks into my pregnancy and I wish I had remembered how stressed out I get while pregnant. I've had a terrible backache for a couple weeks now, and decided to give Icy Hot a try tonight. Didn't think to look it up until after it had been applied, but it may not be the best choice while pregnant. I used a version that doesn't have the aspirin ingredient, but I'm still worried. Anyone use this during their past/current pregnancies?
