Hi, I Am 22 Years Old And I Got My

hi, i am 22 years old and i got my first pregnancy when i started bleeding slightly in the 5 or 6th week, on 3rd day i had heavy bleeding and severe pain and i miscarried, after that all pain was gone i was feeling perfectly normal and still bleeding very lightly, so i visited a doctor so if nothing is wrong with me, she gave me arthrotec tablets to eat thrice a day for 3 days and then come for ultrasound on 4th day. i ate 1 on 1st day then again 1 on 2nd day, today is my 3rd day but i am afraid to eat it because of the severe pain it has caused me, i have no energy to get up or do anything. i didn't take the tablet today but i still have severe pain. is something wrong with me? what should i do? it has been 5 days im bleeding, when will the bleeding stop?
