Feeling off

Im 31w 4d and today i woke up to pack my husbands lunch and make him breakfast at 9:00 am then i went back to sleep and i woke up like at 1:30 pm. I was feel a little off kinda mad so i took a shower and went to the store to buy food but im not hungry at all and i dont have the energy to make or do anything so i just sat at the table and started crying for no reason. Is this normal ?
