clomid over femera

hello ladies! so i did three rounds of letrozole (aka femera) and i started to lose hope as my progesterone levels were steady between 0.4-0.6. i got them checked sunday and they were at 17.4! i was so excited i cried! however, my mom had my doctor switch me to clomid as my stepdad thinks it will be better. i start the clomid next friday and i’m terrified it’s going to drop my levels. had that ever happened to anyone? i’m 9 months TTC and it’s really starting to get me down.
