Thanks for your query.
You seem to be having polycystic ovaries
In this condition, the ovary is studded with multiple small cysts ( follicles ) , and there is a difficulty in having regular menstrual cycles and in ovulation, and hence conception.
Please get yourself thoroughly investigated for polycystic ovaries.
Also, with a negative pregnancy
test, you are mostly not pregnant.
Only a gynecologist could confirm this though, after check up, blood work and an ultrasound
, stress, workouts, etc also could be responsible for your problem.
