Opinion?

So I took 2 tests last week and got faint positives on both. AF was supposed to show on Saturday, but nothing happened till last night/today. Last night when I used the restroom, there was really light brown and pink discharge, this morning there was nothing, about an hour ago it was bright red. I'm supposed to go to the doctor on Friday to get a test done, just curious if I should still go through with it or not. Please no rude comments, just looking for opinions or advice. Thank you.
