Ovastril and femara

I got pregnant 2 times on clomid both times I was not ovastril. After that I went on it bc I was diagnosed with pcos and can’t take metformin (not insulin resistant). She wants to me to continue taking ovastril but this is my 4/5 cycle in a year with me taking on clomid or femara and it’s not working at all. Has anyone had difficulty conceiving wjtb ovastril?

Pcos is my only diagnosis — all hormones are perfect except amh. Which is on higher side of Normal for a women my age.
