5w 3 days miscarriage

Hi everyone 
Not sure if this is the right group to post in but will try anyway. 
5 and 1/2 weeks pregnant and had cramping and bleeding. 
Got worse over night and now have clots therefor I know I have lost the baby. 
I'm from uK and dr wasn't to bothered they just said call back in a week of still bleeding and preg test still says positive. 
What do I do? Do I go to work? Do I make drs app? How long will bleeding go on for? How long is cramps? 
Please help
