Hysteroscopy while TTC, after 4 failed IUIs, Dr said it will help to get pregnant faster...

Hi everyone, so after 4 failed IUIs, the fertility Dr suggested us to do Hysteroscopy to boot the uterus n help to conceive faster...we gonna do it this month n then back to <a href="https://glowing.com/glow-fertility-program">IUI</a> next month...my uterus is fine, doesnt have any cyst or fibroid, no chemical pregnancy, no miscarriage, no etopic pregnancy,not pregnant b4...Uterus linning always around 6-9mm. 
So anyone had done this b4 n got pregnant easier after this??? Pls share ur stories with me, im new to Hysteroscopy, n was so disapointed bc the IUIs wasnt worked...
