2 Weeks after Loop Biopsy

I had a loop biopsy 2 weeks ago and everything has been fine. No bleeding or pain and the normal type of discharge.

However, the other day within 2 hours I had filled 2 pads with blood. I wouldnt normally worry but the amount of blood was ridiculous and there were also clots. 

I ended up at A&E becuase I was really worried but they didnt really tell me why it happened just gave me some tablets to stop the bleeding.

Everything has been fine since and back to normal.

has anyone else experienced this?
