Last month I went for a follicle test and my follicles size was 4-5 mm and endometrial thickness was 6 mm. My doctor said I am having pcos and gave me smartova 50 for 5 days along with productive pcos and productive F.this month again I went for a follicle test on the 12 14 16 day of my period and now my follicle size is 4-6 mm and endometrial thickness is 7 mm. Why my follicle size has not grown.
