Omnipods not sticking as well when pregnant?

Hi ladies! I'm about 5w with baby #2, but this is the first pregnancy while wearing the Omnipod. I've noticed that I tend to be a bit oily (I know, yuck!) the first trimester and it seems that maybe it isn't just my face and hair... my pods seem to not be sticking as well.

Has anyone had experience with this? I don't have any of those "bands 4 life", but should I get one? Is this something that will last all pregnancy or just the first trimester?
