Menopause or what else could it be

Patient: I am 48 years old. Last month my period was just very strange, I had a couple of days with only dark spots and nothing else. This month nothing altogether. I have pains in my lower right sign. I have heat and cold spells. I did a check up in December and the doctor said that I will not be entering menopause for a while. I’m not pregnant. What could it be???

Symptoms: Lower right Pain

Doctor:
