Periods after surgical abortion?

Hey, could someone give me some advice if possible please. I had a surgical abortion back in November at the beginning and I had a very light period in December from 19th-23rd and didn't have another period until 29th January and I have basically been bleeding ever since then. I was advised by my GP to take Norethisterone 5mg twice a day to stop the bleeding and once the bleeding stopped go straight on to the mini pill which I did. A couple days later the bleeding has started again and it's still really heavy. I went back to the clinic to have a scan done and everything was normal.

I am day 9 of bleeding and I feel as if its never going to end I have taken Tranexamic acid to help with the heavy bleeding and I am still taking the mink pill , I have my holiday coming up on 17th March and I really don't know what to do :(
