Concerning symptoms

In September 2020 I had a routine smear which came back with severe abnormal changes. I then had lletz procedure everything fine got my results all had been removed with clear margins. I then had my follow up test in march 2021 which shows all normal no hpv back to 3 yearly tests.
December 2022 bleeding after sex thought start of period happened again then came on period. Fine through out January no bleeding. Now for last couple of times there’s been a lot of blood on the bed no pain. I’m going to book a dr appointment tomorrow as I’m worried. Has anyone had any similar to this. I’m driving myself crazy I’m not due another test till next year.
