Advice please

I have had a miscarriage at beginning of the month I bleed for 5 days and had some pain and then everything stopped. I still haven't had a period I'm getting negative tests. But for the past 6 days o have had dull and sharp pains. The doctor did a wee test and all is normal . She tried to get me in for a scan at the hospital . But the hospital wouldn't do one cause I am getting negative tests. And said the pains must be something else.

What should I do please help.
