Bleeding/Brown discharge

Hi mommies! First time mom here. I am currently 8 weeks pregnant and have found brown discharge, accompanied by blood. I am quite worried as I fell ill recently and if this is a sign of a miscarriage. If I am not pregnant, my period should be here as I do have regular period. I’ve booked my gynae appointment but only available on the 23rd. Can anyone advise please? 🥺#1stimemom
