I'm not trolling, 100% serious question to the gym community.

I'm a young woman, not overweight by any means, but i want to get fit because I'm not 100% happy with my belly and my last bloodwork looked wonky.

Now I've seen tons of women online, talking about how their breasts started shrinking when they started working out regularly... so now I'm kind of worried that it might happen to me? I am completely confident about the way I look, despite whining about my belly from time to time (160m and 63kg) ... any advice?
