My second IUI ladies!

Samantha • 23yo. TTC #1 for 4 years. PCOS. Blissfully married. Hoping our family is going to start with our first IUI cycle.
Went to the RE to see how many follicles we have. He said we have 3 good sized ones for CD10. 9mm 10mm and 12mm. He said to come back Tuesday to check the growth again. What did all of you have? Any of you going thru the second cycle this month with me? Any successes for this cycle lately?
