Spotting but No period????????

So I’ve been noticing something really wierd happen to me the last couple days. I noticed last week that I had brown spotting or brown discharge but I have no infection. It went away for a couple days but now I have light brown & light red spotting but my period is still more than a week away. I have never EVER gone through this before in my life. I’m 20 years old and I know my body and something is off.

I do take birth control and I’ve been taking it since 2019. I have had stress recently but I’ve had it worse in the past and this never happened. I’m trying to think of reasons why this could be happening.

The chances of pregnancy are low though…. I’m on birth control and take it every single day.

Is this normal?
