One inch in a week and a half seems like a very good amount. Stalls in weight and measurements are very common on SB and on most other eating plans. Not sure how much you need to lose in total, but be patient and keep to your plan and I'm sure you'll progress. Remember that TOM can cause bloating = inches and exercise can build muscle where you had none, so that can impact your measurements even though it is ultimately a good thing.
Best of luck,
