Can I ask for a smear - had CIN3 removed last Year

Back in 2017 I had CIN3 removed, last year was given the all clear and back to 3 year testing, over the last 2 months i've started spotting again. Can I just book another smear or should I see my GP first. I don't want to waste anyones time, but I also don't want to leave it.

Hi juggsy1981 you really need to speak to your gp for a referral back to the colposcopy clinic. Take care.

Thank you for your reply, I contacted my GP and got an appointment to see a nurse today. fingers crossed it's nothing.
