Skin discoloration

Olivia

I have been prepared for dark spots on my face and neck, as I read online many times that its normal during pregnancy. Luckily, I haven't had any yet. But I do have discoloration on my butt! On top of freaking stretch marks! Who the heck gets stretch marks on their butts?!?! Anyways, I've somehow his my hideous rump from my husband for several weeks now. (Noticed the dark and red spots around 22 weeks, and 31 weeks now) but he noticed it last night. He laughed at my rear, not realizing how awful I feel about it. Now he's saying its not a big deal, but I can see it, and its kind of a big deal. My ass is awful. And it used to be my favorite asset... For some pun intended.. :(

What do I do? What can I do to make my rear end pretty again? :(
