Using lightening creams during pregnancy?

Is it safe to use the skin lightening creams during pregnancy? My underarms, lady bits, and overall all of me has gotten darker from being pregnant. It’s kind of embarrassing. I look dirty even tho I scrub and shower every day. I don’t wear tank tops or any underarm showing shirts bc it’s scary lol. And I haven’t let my bf go down on me bc it doesn’t even look like my vagina anymore. It’s weird, but I was wondering if they’re safe? I read it’ll go away after the baby if born and hormones go back to normal, but it’s summer and I want to enjoy summer clothes :( I’ve been looking at one at Walmart and my sister is wanting to get me one from a sex shop lol
