HELLO, BERNICE !
The questions you've asked do not have a 1 + 1 = 2 answer, unfortunately. Since you are wondering, it must mean that you may have been noticing changes in yourself lately , is that right ?
I for one began peri-menopause at 38 and just recently went into menopause at age 43 (in three months I will be 44). That's condsidered early but not unusual.
What symptoms are you getting ? Every woman experiences it differently.There are about 100 symptoms, though , but do not worry, you don't get all 100.
By getting a FSH test done, your doctor can give you an idea .(Get complete blood work done, too).They can let you know if you've entered peri-menopause, the period of time which leads you up to menopause.
