Period after Mc

A

Its been nearly 7weeks since my natural missed misscarriage at 11wks( stopped at 9wks) i bled on and offish for about 3wks. Im still waiting for my 1st cycle to return and yet still seems to be no sign. Is it worth calling doctors to see whats going on? I input as mc bleeding as cycle on here and says period should be here today which its not, Iv had neg preg tests since 2wks after MC and i took a ovulation test today and the control line wasnt as dark as some on here and a barely there faint 2nd line. So not sure what is going on and how long its going to take. Im starting to worry somethings wrong as surely id of had period back by now 🤷‍♀️
