Squatting my butt off?

⚪Hula👶👶👶 • left glow for a break. I may come back as some point but for now its taking too much of my time
I have been doing 70 - 75 squats every evening. I have been for about two weeks I noticed yesterday my butt size has gone down drastically. As in a good inch and a half. I'm sad about it.. But should I stick it out? Will I be able to muscle it back?
