Hello Xinyu, thanks for sharing so much. My problem is vaginismus. i could not hv normal intercourse. The last time i did IUI, i had clomid only. 3 pills a day for 5 days. Also, i did not do HSG. My hubby also did not do sperm analysis. We went straight into it.Took clomid, go back for scan on D12, then do IUI, normally on day 13/14. I don't think i produced a lot of eggs that's why the gynae increased my dosage of clomid from 2 to 3 after the 1st round. I knew the 3rd time i did, i had only 1 big one. I felt that my ovulation time was not quite correct as I have 34days cycle and for the 3 times, the IUI was done on D14, which i think could be 2 early as I did not have much mucus.However, gynae felt that i could do it. So, i'm quite confused, whether was i exactly ovulating when IUI was done or whether there were other problems...Hmmm
