Stress can cause many problems in our bodies. Menopause, I don't know, but I do know it can interrupt your cycle. Missed periods are common for young women with problems associated with stress. See a doctor. They are the only ones who can tell you if you have begun menopause.
My daughter has always had an irregular cycle where stress was a factor. At the age of 35 she was convinced she was starting menopause partly because I started my changes at the age of 41. I told her I thought 35 was unlikely the age to be concerned with menopause. Sure enough it wasn't menopause at all and I now have another beautiful grandchild to love.
Get checked out by a doctor before giving menopause a thought. Not knowing what is going on with your own body can be scary. When I started mine at 41 I was afraid I was expecting even though I have had an operation to prevent it. Thank God, that wasn't the case. I love the ones I have, but surely knew I could do without another.
