Thanks PP. I was hoping B6 could sub, and I could skip the mess of the gross suppositories.

No, B6 is not the same as progesterone suppositories. B6 is a natural way to boost your progesterone (it's thought) and can help your body develop a nice, thick, uterine lining during your luteal phase. It faciliates the preparation of your uterus for implantation. B6 also has other advantages such as reducing PMS symptoms, and when you're pregnant, it can help minimize morning sickness. There is no guarantee that B6 will boost your progesterone sufficiently though, and depending on your circumstances, you may still have low progesterone and shorter luteal phases.

Progesterone suppositories deliver progesterone to your body directly in lieu of your body producing it for itself during your lutueal phase and early pregnancy. If you have been advised to take progesterone by your RE / OB do NOT subsitute B6 for progesterone. Not the same thing.

OP here. Thank you both for your advice. Do you know if B6 and the suppositories do the same thing?

Like PP said, some of us are on them because of luteal phases that are too short. I have a longish cycle, 31 or 32 days, but found out after temping for a few months I was ovulating late, like Day 20, 21, or 22. So my luteal phase bordered on too short. On the supps., it's stretched to 14 days.

Luteal, not luteual. Sorry.

I think you'll find many people here have or do. Search luteual phase defect to read some other threads.

Have you figured out when you ovulate or how long your LP is? I've gotten pregnant twice with a 10 day LP so don't be too discouraged.

You can also take B6 to lengthen your phase or try accupuncture.

My OB prescribed progesterone as I'm having 24 day periods. My progesterone was low in a pervious pregnancy, so I did the suppositories. Anyone else take it under these circumstances?
