cervical cancer diagnosed in 2015

I was diagnosed with cervical cancer in october 2015 and had 2 lletz treatments.  Thankfully it cleared and I now have an 8 month old little boy.  since 2015 I have been to see gynea every 6 months for a colposcopy with the last one being in July.  He does not want to see me now for another year but I am so paranoid that it may come back.  Can I request another smear before the year or do I have to wait that amount of time?

If you do it wont be covered and youll have tp pay out of pocket
