Okay, guys... please help me because I’m FREAKING out.

I’ve been taking my birth control pills faithfully for the last 7 years, and this is the first time this has ever happened. I thought I might be pregnant, so I took two pregnancy tests and both came back negative. Then I started having some brownish discharge for about 4 days, now I’m bleeding like I’m having my period; but I’m in the middle of my pill pack.

Has this ever happened to anyone? Should I go see a doctor, or wait it out? HELP!
