Does vaginal prometrium affect blood levels of progesterone? Could 600mg (200 3x p/day) vaginally produce a 12 DPO blood p4 level of 60? My beta is only 3.4, so I know this is probably not viable, but wondering if the prometrium is responsible for the very high p4 level.

To answer you question more data is required. How did you stimulate? How many follicles? What type of treatment?
Other factors besides the prometrium could have elevated your P4. When I use prometrium, I use it orally and not virginally. You will see elevated P4 levels with the oral route. Most of the approved vaginal progesterones do not substantially increased the blood level. Patients using the injectable progesterone may have levels 200-400.
