Who's been on prometrium?

I'm probably going to start on prometrium after ovulation (my luteal phase is really short 5-8 days).

*raising my hand* I've been on prometrium! But I took mine orally (200mg). Are you getting suppositories or are they the little yellow pill thing? I believe those can be taken either way (orally or vaginally). If they are strictly suppositories, then I guess you'll just have to use them vaginally.

I have a sort of short LP (I actually have falling numbers post-O, which is why my OB/GYN wanted me to take the prometrium the same months we were doing Femara). I usually have 9dpo before I start spotting, but then I spot for about 3-5 days. With Prometrium I got to about 11-12dpo before spotting started. But, unfortunately, I still spotted for about 4-5 days after stopping the prometrium. But, I believe I'm one of the minority. Some start their period a day or two after stopping the progesterone.

Good luck! Oh, and with the oral prometrium, I didn't really have any side effects. I took it right before bed at night (which probably helped keep me from feeling those side effects). If you have to take it during the day or multiple times through the day, then I would say stick to vaginal and avoid those side-effects. :)

lots of ladies here have been on prometrium for lp problems - I'm thinking that for most if not all of them it helped to increase the lp.

Good Luck!

I was on Prometrium or progesterone for over 1.5 yrs.
W/o it my LP was about 9 days if I was lucky.
I was started on a pitifully low dose of progesterone 100mg. I upped it myself to 150 plus cream & I got pregnant (ended in m/s), my progesterone was sooo low.
After that loss I requested oral Prometrium, 400mg (200am & pm). I was sick of mess & wanted oral. After a few months u dont notice side effects.
However I switched to 1/2 oral & 1/2 vaginal as vaginal is more effective. My LP was def. extended when taking vaginally. I never needed to stop taking it to get my period, unless I was miscarrying, then it prolonged things.
I never had more than a 12day LP on it.

I've been taking 200mg orally starting at about 4dpo for quite some time. It has extended my LP from 11 days to about 13 days on average. So I'm happy with that. And the cycle I got pregnant (it ended in m/c though) while I was one it, my prog level was super high at 14dpo, so it was definitely doing it's job! Good luck!
Oh as far as side effects, the only thing I notice is dizziness, so I take my pill right before bed.
