Mid cycle bleeding and cramping, help.

So I don't know if I should be concerned or something but I'm on day 14 and have been bleeding since day 11. I've been having a lot of uncomfortable feelings in my stomach and cramping that gets bad at times. Should I be going to a hospital or should I not worry? 
I'm going to my fertility clinic in the morning for blood work to check my hormone levels but I just don't know if I should get myself checked out sooner ?
