Miscarrying? My first pregnancy

Tay

Today I'm 5w2d and this morning I started spotting. I read that it could be common and that I should rest but after my nap i woke up and had to use the restroom. Pulled my pants down and seen what I think is a lot of blood (sorry for the pic) and I look into the toilet and

see this (again sorry for the graphics). Should I go to the ER or just wait until Monday when the office opens?
