Is brown discharge normal? Should I take a pregnancy test?

My discharge is light brown and I’m on birth control pills. The last time I had sex was March 15, 2023 and we used a condom. I got my period on March 25, 2023 and April 22, 2023.

I’m supposed to get my period next Saturday (May 20, 2023). But yesterday and today I noticed I’m having light browns discharge. Should I take a pregnancy test? Or does having your period 2x after having protected sex mean I’m not pregnant?

Is brown discharge normal even on birth control pills? I’ve been on the pill since 2020 and this is the first time I had brown discharge 10 days before my period.
