Brown discharge Help

Amanda

Ok I just got 2 faint pregnancy lines two days apart and second one was darker this morning but I’ve been having brown discharge and a little dark red looking every now and then. Lite cramping but nothing bad or like period. I calculated I should be about 3 weeks pregnant but I’m afraid I’m going to lose it or it was a false positive because of the discharge. It’s not much but enough to wear a panty liner and feel wet down there a lot. Is this normal
