progesterone suppositories

if any one has experience with it can you let me know how it was for you? i just started using them last night because i have a history of premature birth but i'm curious how everyone's body handled it? also did you notice a smell down there? i've noticed today my smell is different and stronger and i don't know if it's because of the suppository or not, it didn't happen until after i inserted one last night and this morning had the smell
