Hello!
It depends entirely on your budget: If you can afford it, go flying. If not anything else, it will motivate you to go on with your studies.
If you are on a tight budget, save your money for the coming expenses (instrument and ME training are going to be _very_ expensive). I don't know your training scheme, but if it is anyting like ours here, you will continue your practical training with basic instrument flying either in the procedures trainer or in the real aeroplane. Especially the procedures trainer is so totally different from flying VFR in a single engine aeroplane that your montlhy training flight is not going to make any difference. You literally have to start from scratch anyway.
So, you like to fly (or miss flying very much): Go flying. But for your training it is not required. (Just my personal view after nearly two decades of instructing).
Happy learning!
