People feel miscarriages and others do not. You would however know if you do Miscarry. You would bleed not spot bleed like you were having a normal period and you would have some discoloration in the blood like blacks and grays. If you do miscarry its a good idea to see your doctor to make sure your body is cleansed the way it should be, so you arent at risk for infection.
I cant answer the progesterone ?, except if you have not M/C yet then your body might still be producing it because you are still technically pregnant.
A M/C can be painful or involve very little pain, it varies. Typically you will have cramping/bleeding/passing blood clots. Your Dr. will F/U on you and test your HCG levels to see if you have had a full M/C. If your HCG has gotten to 5 or below then the Dr. knows it was a full M/C. If your HCG levels are not dropping or you are having pain after they think the M/C is over, it can be a sign there is still something left over your body hasn't been able to get rid of yet.
Sorry for your lose and I hope it doesn't end up being too painful.
