Stress over progesterone suppositories

Melissa • I`m a newlywed who just got married August 23, 2014. My hubby and I have officially been together for 4 years and are trying for our rainbow baby. We lost our first at 8 weeks in December. <3
Anyone else using the progesterone suppositories? I feel like I need to be lying down all the time so it doesn't fall out and I get the maximum benefits. I'm afraid if it falls out 30 min in it won't work. Anyone else stressing or used them before that can give me some hope.
