Boob Size Withdrawals

So as the title says I’ve been on Spiro for around 2 years and recently I’ve been going through a stressful time at work and have neglected to take it (I know it’s bad, I would never normally quit any medication cold turkey but when I’m depressed or stressed I neglect myself, working on it!)

Anyway I haven’t been taking it for around 2 months now and I noticed recently when changing that my boobs are significantly smaller? Is this a thing and if so, would it happen so quickly? It’s not the end of the world since I was prescribed it for Acne and it’s worked amazingly however I’m shocked at the difference and wondered if it could be related to withdrawing from Spiro?
