Should I feel guilty?

Emily • Married. 5 year old son. 2 year old daughter. Pregnant with our last.
I am pregnant with our third baby, which we are super thrilled about! My husband and I are going on a little "baby moon" this weekend and I am feeling so guilty about leaving my other kids 😭 my son is 5 and my daughter is 2. We will be gone Friday-Monday. Are we being selfish by going away for a weekend? I feel kind of silly asking this but I know my babies will really miss us, and I feel mean for going anyway lol is it just my pregnancy hormones?
