i am currently doing a down reg cycle, epu scheduled for friday morning, 37 hours after trigger tonight.

just wondering how many hours your clinic schedules epu after trigger? seems to vary around 36-38 hours... doesnt seem to be a huge variation, just curious to find out if all clinics work within this timeframe or if some clinics trigger earlier/later.

also, has anyone used pregnyl as a trigger? i have used ovidrel & syranel as triggers before, this will be first time using pregnyl. little risk of ohss with this cycle and apparently pregnyl is supposed to be a gentler trigger than ovidrel. just wondering if anyone else has used both previously (or even just pregnyl as a trigger before), and how the cycles compared (egg quality/numbers etc).

thankyou.
