Sweat=boob loss? Possible?

So I work out a lot and i sweat a lot. My sports bra gets quenched in sweat and my boobs seem to be getting smaller. Can me sweating so much be the cause of smaller boobs. ? It’s not from weight loss because I don’t seem to be loosing weight and that’s not my goal I’m already really skinny. I run 3 miles 6 times a week and do weights 5 times a week.

Don’t be rude pls ik this may sound dumb.
