Has anyone had any luck using Chinese herbs?

Me:

Age: 39 (Bf is 29)

MMC at 8 weeks, December 2016

D&C; January 20, 2017 (cytotec didn't work)

7 periods since D&C;, but only able to TTC during 5 of them

1 round of Clomid+Ovidrel

1 round of Clomid+Ovidrel+<a href="https://glowing.com/glow-fertility-program">IUI</a>

HSG results are normal

Bf's semen analysis was normal

Second cycle taking Chinese herbs (after period, and up until ovulation).

NOTHING!!! I got pregnant so easily before (TOTAL surprise, wasn't trying and was even on the pill). WHAT GIVES???????!?!?

Has anyone had any luck with herbs?

Thanks, all
