Hey Nikki,
I just wanted to let you know that I never took my progesterone suppositories and pills at certain time everyday. I just made sure to take them everyday. I'm sure you'll be fine if you ever need to wait a bit.
I am on the progestrone shots as well and my nurse told me to take it a hour from each other. Example: I take my shots at 8, so I have the option to take between 7-9. 7 being the earliest and 9 being the latest. Hope this helps.
