This does not bode well. You urgently need to go to the doctor. And it is better not to delay. My friend had a similar situation, she went to the doctor when her period had been going on for almost 3 weeks. And when she was admitted to the hospital, she really regretted that she did not go to the doctor earlier.
Of course This Is Not Normal !! Call the ambulance and the hospital, for any abnormalities during pregnancy, contact a doctor, health to you and your baby !!
