Trigger question !

How big where your follicles when you triggered and did u end up getting pregnant? This is my third and all 3 <a href="https://glowing.com/glow-fertility-program">iui</a> my follicles when 18 when triggered..... i read the best is 22 mm and up.... maybe thats why my <a href="https://glowing.com/glow-fertility-program">iui</a> s are not successful 😢🤷🏼‍♀️
