Does anyone experience brown discharge when wiping or blood but you don't see it in your urine?

I get this most days. I'm very scared cos doctor is making me wait to take another pregnancy test tomorrow as she reasons I may miscarry/ miscarried already. She told me Monday so that night I risked taking a pregnancy test come back positive so hoping this one does too. Feel so pregnant though- have all the symptoms and all the growth pains. Has anyone experienced anything simular? Or can shed some light on this matter whether good or bad? I'm praying every moment of every day right now. It's my very first pregnancy x
