Feeling needy ? Clingy ?

So I'm on my first trimester this is my second pregnancy , and even tho I'm not feeling sick as of right now lately I have been feeling extremely needy and lonely my hubby works out of town I see him maybe every three weeks this is how our relationship has been and I'm already used to it . Until like a week ago I wake up in the middle of the night feeling the need to talk to him make sure he is okay or even if he doesn't respond back right away I get extremely emotional is this normal ?
