The only way to assess your fertility
, given your age, is to assess your ovarian reserve
This will test the capacity of your ovaries to produce good quality and good number of eggs.
Given your scanty menstrual flow, it is likely that the ovarian reserve is diminished, which generally happens in women with age.
Ovarian reserve is tested best by measuring the level of a substance called AMH.
ALso, a pelvic ultrasound
scan done transvaginally on the second day of your cycle ( can be artificially induced with Primolut ) will show the number of egg follicles in both ovaries - antral follicular count.
Lastly, follicular monitoring will tell you if you are ovulating.
