I am having pcos but for last 6 months my period is coming regularly. But my follicle size is not growing. Beginning of the treatment it was 4-5 mm then I started taking smartova L for 3 months and went for a scan and it was 9 mm. Then my doctor prescribed me fsh injection for 3 days after taking those injections I again went for scan and then it was 11 mm. My doctor said it is not perfect. Today I am going to take hcg injection. So my question is why am I responding slowly. And for how many cycles do I have to take injections to get a perfect follicle.
