Bleeding after a colposcopy and biopsy

I'm new and after suffering for years with period issues I have finally had my first investigation last week.  Since then I have been bleeding heavy with blood clots.  Is this normal?  I also had period like pains which kept me awake at night and on constant pain relief.  The pain has eased but the blood flow is the same. I am very used to painful heavy periods but is this normal?
