5dpo and I'm an emotional wreck!

I am 5dpo and I have never been so emotional in my entire life. I have had 3 melt downs today I mean to the extent of bawling my eyes out and yelling like a crazy woman over stuff that normally would not bother me. I definitely wouldn't start crying over it.

Is it possible to even see signs like this, this early?

My hubby and I just started ttc and I am very new to the glow community!
