Abnormal smear


So I had my 1st smear and it come back with board line abnormal and hpv and had some vinegar water and cells taken, I had another smear a year later and it come back clear, then 3 years later I had another routine smear and it come back with high abnormal cells and hpv, I have to have the loop (I think} treatment under a local, now I'm absoulatly petrified I will have another abnormal smear and ill be back in for treatment, if I do would it be a possibility to have a hysteromy as I have my children and don't want any more or will it be a no, any advice would be greatly appreciated thank you in advance
