Laser treatment stopped my periods. How is this possible?

I had laser hair treatment on my bikini area twice now. The first time my period was late and very dark. The second time my period is very late. I. Am definitely not pregnant and before this I was regular. I have also read reviews by people online saying they became infertile or their periods stopped too. However Dr's and my clinic keep on saying it should only penetrate the hair follicle yet this is not my experience. I am worried now. I feel like I was not told the truth. Have I killed my cells?
