Trying for 2.5 years.

Anyone have any advice or vitamins/fertility boosters that would help. Ive taken prenatals for years and coq10 for about 4 months 400 to 600 mg a day. Coq10 has definitely got my cycles more regular. Been to a fertility dr a million tests later nothing wrong all tests normal no pcos or endo. Only thing was egg quality or maybe not ovulating all the time. 1 cycle of femara and got preg still miscarry. Focus is on egg quality. Had 6 miscarriages within 2 yrs.
