I just wanted a bit of advice/reassurance and I am so worried that it's affecting me now.

so the two months I noticed a change in my body. My periods have changed to just 24 hours long but heavy the last two cycle, on top of that I have had pelvis pain/pressure ( nothing unbearable just noticeable) some bloating and period type pain. I was concerned and went to my dr who done a pelvis examination which he said was fine and referred me for w scan. During this I mention I was late for my smear by around 7 months, terrible I know but I had it booked and had to cancel as my daughter was unwell and then I forgot! Big mistake.

I had a smear the day after my appointment and bloods, all bloods have come back fine but I quickly got a letter saying I have the hpv virus and high grade severe dyskaryosis. I have my colposcopy next week and have been told I will have treatment that day. I am so scared because I have left my smear late plus my symptoms for the last two months that it has turned to cancer. I am terrified.

has anything else has this on top of my symptoms and everything be ok?! I do not have any bleeding between periods or after sex. Just the pelvic pain and a change in cycle length. 
 

Thank you!
