What to expect when miscarrying at 5 weeks

Hannah
I found out last weekend I was pregnant , I was 5 weeks yesterday , did a test again yesterday morning and came out postive, went to work and in an hour I was bleeding. Spotting mainly and it has continued today and is  more than spotting. 
When reading about miscarriages I imagined to be heavily bleeding and changing consistently and being in a lot of pain that is what other blogs are saying online. Of which neither I am experiencing.
If you have experienced miscarriage at 5 weeks what should I expect ( clots , heavy bleeding) as I am struggling to get my head round what is happening . Midwife has said to sit it out till Monday 
Any thoughts ?
