lost 10 pounds in 4 days?

Al

I just got my nexplanon out 4 days ago and within those 4 days I have lost 9.6 pounds. I'm aware that most of this is water weight and bloat but im kind of concerned, I'm never hungry, if I even think about food it will make me nauseous. Is this something I should bring up to my doctor or should I just wait it out and see if my body stabilizes?
