This is my first time of posting here. I just turned 41, but for the last two months, I have been experiencing waking up in the evening with extreme hot sweating, which is like some sort of fever. For the past couple of years, my menstrual period has been very slow and short that only lasted for 3 days. I have gained so much weight but I do try workout 3 times a week. I have never missed a period, except for this month. I am now a week late on my period. At what age will this period menopause starts. Is getting irregular periods normal among girls? I hope I am not pregnant.
