I was 36 at the time I went through chemo. I had CAF every three weeks. I lost my period after the third treatment. I never got my period back, but some women do. My onc said I was just on that borderline, and could go either wey. They really recommend you use birth control religiously for two years after you lose your period and have your homone levels monitored, especially estradiol and FSH levels. The older you are, the more likely that you will not get your period back.
Of course, hormonal birth control is a big "no-no" now that you've been diagnosed, as is hormonal management of menopausal symptoms. Some women choose to have a total hysterectomy. I'm still considering it, but haven't done it yet. It's a cinch the parts aren't working anymore, after 12 years. Don't know if this applies to you, but... A few women go on to have babies after they are diagnosed, but this is a risky undertaking and should be discussed at great length with the doctors to fully understand what your individual risk of a recurrence would be. A few women also use hormones for menopausal symptoms, as well. Again, this is something only you and your doctor can decide is safe for you. There was a lot of coverage about Suzanne Sommers continuing to use HRT, even though her doctors advised strongly against it. She seems to be doing okay. I know that I would never be willing to take that chance.
Hope this helps.
Good luck to you...
