I just had an IUI Saturday morning. Wednesday prior at the ultrasound I had 2 follicles ready at 23mm and 20mm and 3 more that weren t quite ready yet. My endometrium was at first measured at 6.5 and then he said he got a better view and it looked more like 8.5. I took the trigger shot at 9:30 pm on Thursday and went for the IUI Saturday morning at 8:30. My husbands count post wash was 15 mil. What I am concerned about is the endometrium thickness. Last year I had two miscarriages within 3 months of each other. The first one made it to 12 weeks but the second only made it to 4 -5 weeks. I am wondering if the endometrium could have been to blame but it could also be my age. I am 36.
