I am having all pregnancy symptoms and I am having some spotting and it's a brownish color I don't know if I should go to the doctors or just take a test. I am on the pill so I'm not due for a period yet

There aren't any "pregnancy" symptopns other than astopping of the period in most cases, growing abdomen... changes in your breasts, and a baby eventually popping out.

The rest can mean any number of things or even nothing.

You have to wait until you are a few weels late for a period and then do a HPT. Anything before then is likely to get a false negative.
