Brief Answer:
It will be detectable upto a month in your blood

Detailed Answer:
Welcome to HCM. I am sorry but you will prbably test positive as it takes at least 4 weeks to wash out, there is a slight chance that you have cleared it with the hydration, but I would not bet on it. And if they check your hair follicles or nails for the testing this will be positive for at least 6 months. I hope this helps and good luck.
