Three days after having unprotected sex I felt extremely tired n slept for almost two days.. and now five days after having sex I'm spotting brown? I'm not trying to get pregnant but would these be symptoms?

Symptoms very, very rarely appear that quickly.

If you are having unprotected sex you ARE trying to get pregnant.

If you are having a discharge you might want to consider being tested for STDs.

LMAO! You're not trying? It seems to me like you are. So what do you figure will happen then?

And yeah, it's way too early for symptoms. Maybe you're getting sick... maybe not. Maybe it's time to see a doctor.
