Does your skin become more sensitive during pregnancy?

I have a cut on my arm, which is kind of healing. I put some bepathen on it and a band aid (the elastoplast, fabric ones) I took it off the next day, and all where the sticky part had been was red and blistered and yuk in general.

I know I used to have reactions to the plastic type bandaids when I was a kid, which is why I use the fabric ones. They've always been OK in the past, so I'm wondering if it just because I'm pg?
