Metformin, Clomid & HCG trigger shot.

Hi ladies, just had another cycle with this combo and for the first time I finally have somthing going on. My E2 level is 1370 and I have 2 folicles at 18mm. One on each side. I'm just after any advice and /or stories....has anyone on here had this before and if so was it sucessful for a pregnancy of twins or just one bub. Im assuming both will release due to trigger. Thanks in advance for your time :)
