Bad body odor

I'm 32 weeks pregnant and have noticed that I've been getting bad body odor in my groin area. I'm a very clean person shower everyday. But I feel like as soon as I get out the shower I'm already sweating down there and the B.O comes back. I've never had this problem before. So I'm guessing it's the hormones? Is any one else going through this? And how did you manage it?
