Monday 8 DPO should be just fine. Kind of concerning that your doctor doesn’t know the WHY behind CD21/7DPO being the “same.” Might want to switch OBs!

catmom17 :  ah ok, that makes more sense. I’d be a little less concerned then, too. Still kind of … unsettling though, especially since she’s likely ordering these labs for other women that don’t have a perfect 28 day cycle.

catmom17 :  you’d be fine at either. During my treatment cycles, my clinc would do my progesterone test anywhere from 5dpo to 8dpo. Progesterone sort of plateaus towards the middle, so you have a bit of fluidity there.
