10 days is not enough time in my opinion. For any diet or routine to start showing results it takes at least 3 weeks. If you’re young, two days, lol. If you’re older, 3 weeks. Yes, age makes a difference. 
A slower metabolism is to blame for that. There are of course exceptions to this rule…some people shed weight miraculously…like its no problem at any age. But the general rule is, with age your metabolism slows down.
^ This is very much a possibility. I guess your body has stopped working hard and has gotten very comfortable with the current routine.
Adddd the protein njgal! Fish is the best!
The HIIT is a good idea…most spinning and cardio classes are conducted that way too.
njgal, I know you want to see results because you’re working so hard but you have to be patient. Some people find it harddddd to lose weight after pregnancies. So, my advice is…do not get distracted by the scale. Put it away for now. I want you to keep working towards your goal but do not even think about checking your weight until you’ve given yourself at least a month on your current regimen.
One month minimum.
