Bleeding 3 weeks after smear

I went for my smear on the 27/09 and ever since (3 weeks tomorrow) I have had brown spotting which has turned into red but not as heavy flow as a period. But it hasn’t showed any signs of ending. My smear results have come back normal which I am grateful but I’m also trying to conceive after a miscarriage in July so I’ve not ovulated either.

My GP has confirmed no infections and I don’t have a cervical erosion. Could the nurse doing the smear have hurt me? It was a little uncomfortable. I’ve never bled after a smear before. I went for my smear a few days after my period too so wasn’t due on. It’s making me miserable!!
