I'm sixteen years old, I get my period the beginning of each month, 3 weeks ago I had unprotected sex.
And now I'm having a weird brown spotting, what does this mean? Does this count as my period?
Is it because I don't have enough fluids in me?
Answer ASAP please and thank you

Brown blood is usually old blood, blood that's been in your system for a while, and it's your body cleaning itself out.

This link explains it far better than I can.

Is your period late? If so, a pregnancy test is in order.

It was just about on time, but it's just brown, and it's only during the day not at night I put on a panty liner and there's just a little in it every day. But thank you I'll look at the link
