Mixed emotions 😬

I have a 11 month old stepdaughter that is constantly sick and is still getting used to staying the night off with her mother so she tends to not sleep during the night anymore when she comes back. Anyways, I took a pregnancy test last night as a joke and there was a faint line, I was excited at first because we have been trying for about 5 months now but at the same time having 2 babies to tend to by myself is freaking me out. My husband is about to be deployed and I have no clue on how I’m going to be able to do this alone.
