Unfortunately stalls happen regularly and the closer you are to goal the longer they seem to last, I know of a couple people that have been in stalls that lasted up to 8 weeks. Just remember as long as you make all the right choices and start moving once you are okayed to do so, it will come off.. I promise. In the meant time take measurements and give the scale a vacation. It can completely deflate you and is not a reliable source of progress validation.
