Smear came back abnormal again

In October I had laser treatment of CIN2 cells in my cervix. I got tested in May again from a different hospital and it came back clear. Then I got tested again in April by another hospital and it has came back as mild changes in my cells and HPV is still present. I’m only 25 and this is really scaring me. Will it effect my chances of having a child? I want nothing more than to be a mum. I convinced myself that my partner (we have only been together 7 months) shouldn’t have to be burdened with it but he’s been fantastic. Which is a relief. Has anyone else had this? I’ve rang the doctor and I’m waiting on a call back. My nerves are threw the roof.
