Alternating Assisted fertility meds 🤔

Hello my doctor had me on clomid for three cycles I ovulated each cycle but didn’t fall pregnant after that she put me on letrozole I ovulated but low and then this cycle she is suggesting I alternate meds every month clomid then Letrozole then Back to clomid I have 6 cycles if I don’t fall pregnant then she said fertility specialist is next.! 🤦🏻‍♀️ TTC is so overwhelming especially with no support or understanding. Has anyone ever alternated between these two meds ????

Update: she also gave me few more options Like that mad anything better I rather her suggest.! She said if I want I can choose to take the meds now alternating or take one three months and the other three or take only one of my choice the whole six.! 🤷‍♀️
