One thing I've learned in the 19 years I've been quilting is:
There isn't anything you MUST do--every quilt is unique. There are no rules that apply all the time. It's your quilt, so you know what's best.
So, you don't need a stitch regulator to do FMQ--it's a nice extra to have, but beautiful quilts have been made on machines without them. Your skill and talent make your quilts beautiful, not special gadgets.
Enjoy!
