It is definitely possible. I very rearly hold a lot if any water at all on just about anything, until I start messing with crazy stacks (about 6 -8 compounds at once)
Depending on my diet Insulin sometimes makes me hold water.
But to your question, you are still holding water yes. I mean only you can tell bro, Just look into the mirror. Does it LOOK like your holding water? If yes then yes your holding water....no need for a rocket scientist.
You'll be fine.
