I'm worried about my breasts

Hello. I'm having trouble with my freckles these days.

I'm 6 months pregnant and they say that when you're pregnant, you get a lot of freckles and your neck and armpits get darker, and it really is.

Many people say that their breasts disappear after giving birth, but I keep seeing them, so I'm worried about waiting until after giving birth.

Should pregnant women just wait?
