weight loss stalled

just wanted to know when most people have a stall im almost 4 months out and have lost 70lbs the scale keeps going up and down 2 lbs for the past two weeks im not doing anything different. just wanted to get some advice

Stalls can happen any time.  One week out from surgery or one year out.  Make sure you are following your doc's rules and this too shall pass.

Stalls suck, but are part of the process.  You have done well to lose 70 lbs!  Keep your protien up, carbs down and drink plenty of fluids.  I spent an agonizing 10 weeks in the 150's bracket...didn't think it would ever drop but finally did.  It dropped quickly once I got over that hump!
