You should not play in a consecutive way,if you see that you keep losing it is better to quit for a bit and take a good rest before coming back,you will see that things can change when your brain is more concentrated than not,also you will be more focused on where to quit and call it a day,if you keep playing continuously it is only natural to keep losing,that is my personal experience back when I used to play slots,it is a long time since I don't play anymore.
I did not say that I play consecutively, I said week/month means that it is an overall stats during that time frame.
Even if I played one time only during November and I lost all my money then I'll say I have bad result in that month.
I know how to control my gambling activity and I'll always stay in my own limit both limit of time and money.
