Progesterone Suppositories

I completed IUI on Sunday. Tomorrow (Thursday) I begin my progesterone vaginal suppositories. I have to use 2 per day. My thought is use one right before I go to work at 7am and then use another one at 7pm. My question is do they leak? Will I need to use a panty liner? Also are there any side effects? Thanks !!!
