I had a late miscarriage in October. I 'thought' my period had returned on 2nd December this month but then it turned out just to be a couple of hours of very 'light' bleed.
Then on and off from then, I've had random red or pink spotting, sometimes a little more than spotting. I've had spotting at random since mid/late November.
I'm getting a bit fed up now, just sat on the loo recently to discover another 'light' period bleed, only a couple of weeks on from the first.
AIBU to ask my GP to make sure this isn't cervical cancer? 
I sound intense but my dad's mother died of it at 25. I never knew her and I don't know him, so not really much to go on medical history wise. But cancers on both sides of my biological family are common and at a young(ish) age too.
I stopped bleeding 5 days after losing my DD, and 7 days after that it was completely normal, no spotting whatsoever etc.
Then the random spotting started in late November
