Anyone NOT buying a lot of maternity clothing?

As
So I own a shit ton of clothes. Like closets and dressers full. I cringe thinking of spending any money on clothing I won't wear that often. 
The only maternity stuff I've purchased are some leggings. A lot of my tops are oversized and flowy and I'm hoping those work out for when I'm larger. I also really hope my maxi dresses and maxi skirts can be used. 
I'm just nervous because DH and I are saving money and we can't really afford a bunch of expensive maternity stuff. Anyone else gonna try to convert some of their wardrobe to work? 
Pre preggo im a size 10 so I know I'll have to buy some shorts cause those won't work but im hoping that's all.
Also I tried on some maternity tops one day and they made me look gigantic! Lol
