I'm 31. Changes n period, severe breast tenderness, hot flashes/really cold, fatigue, headaches, what could cause this? Mom is post menapausal at 47

Flaming June. Your symptoms are nonspecific to a particular condition. Start with the basics : sleep, nutrition and stress management. Hot flushes may result from hypoglycemia and low thyroid (hypothyroidism). Fatigue may be from both of these and poor sleeping (time and quality). See a caregiver who is willing to tackle the whole patient and not someone who will only test your hormones. Good luck !
