Brownish stuff, could I be pregnant?

Question

I had sex on December 1st, the maybe a week later I had clear slimey discharge. I then had sex a few days later. So it's been like three weeks since all of this. Today I noticed only when I wiped that I had brownish to very light pinkish discharge. I did take a pregnancy test a week ago, but it came out negative. But now I'm starting to wonder. Do you think it's possible that I am pregnant, or could this just be a light period? And when is the best time to take another pregnancy test. Thanks everyone for any kind of help on this matter.

By the way my periods are irregular. Sometimes I get them once a month, sometimes once every two months, there's no telling.

Answer 1

if you test right now it wil tell you for sure!

Answer 2

When are you due for your period? Without that info, it's hard to say. But, it's always possible.
