IUI experience... please, please respond!!!

Melanie • Rainbow baby girl conceived with the help of science and born 5/23/17, pregnant with baby number 2, due August 29th
I'm in the waiting room at the doctors office getting ready to do my first <a href="https://glowing.com/glow-fertility-program">IUI</a>. I had the HCG trigger shot yesterday, and had 3 big follicles. We are doing <a href="https://glowing.com/glow-fertility-program">IUI</a> back to back today and tomorrow. I'm wondering how many people had success their first time, and if you didn't your first time, how many times did it take you? Also, did you have more than 1 follicle, and if so, how many babies did you get pregnant with? Please respond! Thanks in advance!
