My IUI newbie story...

Hello ladies, first IUI scheduled for this Saturday... was on 7.5 Letrozole days 3-5... ultrasound today showed 3 mature follicles around 18-19 mm ready to go! I trigger tonight, and IUI Saturday... dr also advised that my lining looks very good... I’m 42 Y/o I’m hoping this works, been TTC for almost 1 year. Is it possible I could ovulate these 3 eggs? Yikes! Anyone else have a success story like this? Blood tests show I have high FSH, but adequate AMH... hubby has low morphology sperm. I feel I have the eggs, but they are low quality and or hubbys sperm is not puncturing the egg surface... anyone else going through a similar story???
