2nd IUI- short cycles- unexplained infertility

Ra

Hi everyone,

Im having my 2nd IUI this Friday. Due to my short cycles I take 5mg letrozole day 2-6. Today was day 7 and I had 2 19 mm follicles on my left. Last month I had 2 18 mm, 14 mm, 12 mm on my right and one 12 mm on my left and the IUI failed. Just trying to find anyone who naturally has short cycles and conceived with IUI and if any of these results were similar. Any feedback or advice is appreciated.
