Advice please

I am new to the forums, but have read a lot! I could do with some advice please. I had CIN 3 diagnosed after my first smear last year. I underwent lletz and as far as Im aware, all was removed… I do have a follow up smear in just under a month though.

Since the treatment, I have been bleeding after sex. This last time being the longest - I’m on day 5. I’m not due a period yet, and I’m now extremely worried that the CIN has come back!

Anyone else had this and it not been related to CIN?? Or anyone she’d some light on other causes. Thank you xx
