Is this bleeding after Cauterisation normal?

I had my cervical cautery 12 days ago, and ended up back in hospital with a pack in a couple of days after, but I've been out now for 8 days. I only had a pink discharge with a little blood every once in a while but this evening I have had cramps and a little heavier bleeding. The cramps aren't that unlike to my period cramps, but my period isn't due for another almost two weeks. Is this normal? Should I do anything, contact my clinic or the doctor on call? I'm pretty worried, as I'm meant to be flying to the USA in another five days. Please, any advice would be welcome.
