Pregnancy Smell!?!?

This is my third pregnancy, first one in a super hot state and first winter baby. This is also the first time that I have had a smell that just lingers even after I bathe, and I rub and scrub  everywhere twice to get rid of it. It's not a bad smell and my SO can't smell it, but it is really starting to bother me! Ugh this has just been a weird pregnancy and now this inescapable smell!
