Hi my name is Ashleigh and I have had unprotected sex and I am concerned I am pregnant! I had complete unprotected sex on february17 and I still do not have my period Iam getting brownish discharge and am concerned about that as well... I don't want to take a pregnancy test right now... what should I do?

Why not?

You should take a pregnancy test as soon as possible, and in the morning if you can. That's a good way to get an idea.
The only other thing you can do is see your doctor.
