3.5cm dominent follicle or cyst?

I'm having trouble figuring this out, can anyone help me? I received this as my test results from my ultrasound that I needed before starting my clomid.  Will they cancel the clomid usually for this kind of result?  Any input would be great thanks! The words definite and probable are confusing me and the "some heterogeneity of the uterine echogenicity", what is that?

The uterus is within normal limits in size.  There is some
heterogeneity of the uterine echogenicity but definite focal
demarcated lesions are not clearly identified.  The endometrium
measures 12 mm.  The ovaries are visualized and there is a
cystic-appearing lesion of the right ovary measuring 3.7 cm.  This
could represent a dominant follicle with smaller subcentimeter cystic
structures noted bilaterally.  No other abnormality of the ovaries is
seen.  There is free fluid within the pelvis.

CONCLUSION: Free fluid within the pelvis and probable dominant
follicle of the right ovary.  No other definite abnormality is seen.

Hi,
Before starting clomid it is necessary that no cysts are present in the ovary. You can wait for spontaneous regression of the cyst or take pills for its regression. It may be necessary to postpone taking clomid. Consult your Doctor.
Hope this helps.
