Post abortion bleeding in less than two weeks

Patient: I had an abortion on 10th Oct. and bled for two whole weeks straight and when the bleeding stopped i had sex. On 06th Nov i had very slight bleeding and light abdominal pain and i thought it might be too soon to get back to my menstrual cycle since its only been 12 days after my periods after the abortion. should i worried?P.S My periods have been regular before the abortion
