I had just had my period and after it ended I started have a brown discharge only when I use the bathroom I have not been having any pains am I pregnant?"

Is there odor?

No

Brown discharge is normal after a period. They call it "old blood". I don't think you have anything to worry about as long there isn't a bad odor and your periods are normal.

It's normal.

As above - purely this is the "clean up " after a period, you will find that it will not always occur but is completely normal.
