Write Away

For me it depends on the story. More character-driven ones tend to be less planned out because I never feel like I really know my characters until I start writing. Ones that feel more plot-driven can be more rigidly outlined, but that usually just entails a list of scenes that I want to write at some point. I don't usually plan it out to the end. I like to figure that out as a write.

One thing I always, always do is write from beginning to end. I never write out of order.

It took me some time and a lot of experimenting to figure out what worked for me. I think you should play around with different levels and kinds of planning and see what feels comfortable for you.
