You'll wait for your period to come, ~ 2 weeks after your trigger shot. Then you'll start FET prep, which is MUCH less intense than stimming. You'll take estrace (estrogen) pills, starting on day 3 of your cycle, and you'll go in for ultrasound and blood work every 4 days or so. Eventually, when your lining is thick enough (maybe ~ 2 weeks into your cycle), you'll start progesterone injections. Then 5 or 6 days later (I'm not sure of the timing exactly), you go for your transfer. You continue the progesterone (and maybe the estrogen, not sure), until your beta 8-9 days later...
