New to the forum and not losing..help!!

Lousover

Hello all, I love myfitnesspal but never used the forums before. Wondering if anyone can advise I'm trying to lose a bit of weight. Before I had my child five years ago I weighed 64kg I now weigh just under at 59kg, aim is to lose a stone and get to around 8stone. I've been logging with MFP over the last month and lost nothing although I have done previously. I run 3k three times or so a week and do exercises at home. I have lost on inches slightly, waist is now 27.5 inches, hips 33 which I'm happy with. I just really feel my upper body is not great, stomach is flabby and my arms feel huge yet when I lose weight they always feel and look better. Not sure what to do. I appreciate you cant spot reduce but...help!!! Thanks
