On 10th day follicular monitoring result shows rt ovary follicles sizes 19, 18, 18, 17mm and endometrial thickness 7.7mm. plz tell me is it normal. m ttc?

Follicle stimulation: This is normal if you are stimulating for ivf. If you are doing an IUI cycle this may be too many follicles.

No: The sizes of the follicles are fine, but the uterine lining is thin. Normally by that time, especially with follicles that are large, the lining is closet to 10 or 12 mm. That could be a problem. You might need a different type of treatment.
