Hi, I am 19 yrs old, got an abortion done on 5 Jan 2012. The doctor gave me mifeprin tab & I took it that very day. There was some bleeding. On the 7th January 2012 the doctor gave 4 pills of misoprostol vaginally & bleeding went for 4-5 days. After a week or so I started bleeding for 3-4 days. The bleeding was normal period bleeding. Now it's been 4 weeks & I haven't got my normal period. Should I be worried?
