You know how they say that pregnant women glow? Well, that's just your skin overproducing on oil from all those hormones. For some lucky pregnant women, this translates into a sudden reversion to pimply adolescence, even for those who never had a zit in the past.
While your face is busy breaking out (or if it isn't), you might find your moles and freckles getting darker. And skin tags growing all over the place. And your nipples and aureolas getting darker. And skin tags growing on your nipples. And then those skin tags getting darker. But this is a family friendly website, so I'm not going to draw those.
