Help please - something wrong with my mining

I have been mining gulden for a few weeks now. I usually get 50 - 100 Gulden a day with a hash rate of 11-12Mh/s. However, I have got no Gulden for 8 days now, which is really odd. I am mining on Windows 10 using a 3700x.I saw a popup the other day saying "Incoming funds" but when I clicked on the app none had been added. I think something is wrong but I'm not sure what or how to troubleshoot it. I have tried uninstall and reinstalling the app. I have tried restarting my PC. Anyone else had this
