Had currettage at 6 weeks after ivf. how long should i wait before fet treatment?

FET: You need to wait at least until HCG is zero and you've had one normal cycle. Your doctor can be more specific.

Next cycle: You can start the preparation process as early as your next period as long as you are psychologically ready and HCG levels are down to 0.

1-2 month: I suggest you check your HCG level one month after D&C if you started your normal period. If your HCG level is less than 5, you may start your fet.
