Dark skin?? Help everyone please ๐Ÿ˜ฅ๐Ÿ˜ž

Okay so I'm 35 weeks pregnant and I've noticed that my neck, underarms and the inside of my thighs and around my vagina have turned really black, and I shower everyday and spend a good 10 minutes scrubbing each spot and I see no difference, I was just wondering if any of you ladies are going through this and what I can do to lighten up my skin, I'm so embarrassed to even walk around in my undies cause it looks like I haven't cleaned between my thighs in years. ๐Ÿ˜”๐Ÿ˜”๐Ÿ˜”
