No menstruation yet up to this day :-(

Hi Ladies i am 46 yrs old & been married for 5 yrs now & still ttc.. My main problem is that I used to have a regular menstrual cyle 28 days but this time its been 51 days since i had my last period. I tried a home preg test but negative. Been to the hosp but the Hgc result is negative too. OB doc said I had a blood in my ovary & she gave me progesteronemedicine but I didnt take it. Could it be that im in my early menopause stage? Please help
