Hi I understand your concern. You can contact your gynae n undergo a hormone therapy for regulating the menses. You can try these Home remedies to regulate it the natural way. Have a glass of unripe papaya juice daily except on the days of periods. During those days you can have carrot juice. You can also have parsley juice regularly, it also gives wonderful results. Try to do yoga poses like butterfly pose, cat n cow pose, bow pose. They too help in relaxation n contraction of your uterine n pelvic floor muscles hence keeping the cycle regular, also eases the pain.

Hello,  kindly consult a gyanec for the date issue. Regarding weight loss kindly give some more information about your meal pattern, your exercise pattern, so that I can guide you for the same. You can message in personal.
