Hello,
These symptoms can be due to premenopause. Symptoms of premenopause are irritability and mood swings,hot flashes,night sweating,irregular periods,decreased blood loss during periods,dry vagina,breast heaviness and tenderness and joint and muscle pain.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I do know that starting stages of menopause cause your menstral cycle to be irregular. To that point I'm not sure if your experiencing body temperature changes as well or not.
