I had a surgical abortion 4 days ago and had little to no bleeding. I have been in a lot of sharp pain in my lower abdomen and lower back. I am out of the ibuprofen given to me from the clinic so last night I took a Acetaminophen and hydrocodone bitartrate 500 mg / 5 mg and went to bed. I woke up the next morning in a pool of thick blood and hurting. Is this normal? Or should I be concerned.
