Miscarriage advice

Hi ladies,
I have just had a miscarriage at 6 weeks. This is my first ever pregnancy and I'm unsure what to do from here. I have heard you need to go to the hospital to make sure everything is out so I don't get sick. Is this true?
Also if it is, do I need to go to hospital or can I wait until Monday for a gp appt. 
Thanks in advance!
