Bleeding in pregnancy

Emma
Ladies I'm on pregnancy number 4 . On the 29th September I had a bleed which took me by surprise as I've never had anything like this before .
I went to hospital and a scan was done , Baby was happy and all was ok.
My bleeding stopped 3 days later on for me to have another bleed Sunday just gone . 
I've told that it's nothing to worry about as the blood is brown . 
Has any other Mums gone through similar at all and I can't help but , worry x
