Bleeding 4 weeks 6 days..

Jess
So, I panicked as I had fresh blood the other day.. Went to a&e and they scanned me and said it was too early so I'm not booked in for the 19th for another scan.. I've been bleeding brown blood on and off since only when I wipe sometimes heavier than others.. I've been so so worried, my mum said she had bleeding st this time with me and my sister.. Do you think it could run in the family.. Or am I being ridiculous?
