Brown spotting turned to red?

For a few days I have been having brown spotting and brown mucus and today the brown has turned to really watery red, like there’s alot of fluid and it is red now, it looks like a normal period at the moment
I have had more or less no cramps
And i just got back from A&E because I was so scared and they have not helped at all
Has anyone had this and NOT miscarried?
I’m really worried :(
