Anyone have any experience with progesterone shots in oil? I have had 2 early miscarriages and doctor suggested starting progesterone shot in oil. I had my first one last week (Monday), period was due on Monday, - was told to take pregnancy test, if negative, discontinue shot. Have had all symptoms of period, did test, negative, didn't do shot, 2 days later, still no period but symptoms. Doctor told me progesterone can delay period but for how long? And how do you calculate your days then?
