I wouldn't worry about until something happens. My wife started at the same weight as you and now she is 150 pounds with no plateau. i have lost 80 and have had a two week stretch with only .5 pound loss but that was it. Just stay focused and eat good and see where it goes first! And congrats on your healthy choice of life now!!
