Nervous about going into labor!

I lost a huge portion of my mucus plug on Saturday, and each day since I've lost the little remaining pieces of it. The last two days I've also been having pretty bad diarrhea. Im pretty sure my baby has dropped too. 
I just have this feeling that this baby is coming soon and I'm FREAKING out! Is anyone else freaking out about becoming a mom?!? I'm 38 weeks.
