Pregnant and hormonal

Amber
These past few weeks I've had no patience, I work with the general public and I've always been able to keep my cool but lately I feel like I'm going to freak out on the next rude or stupid person I have to deal with. 
I'm just about 30 weeks and I really hope it's just the hormones and I'll go back to my normal pleasant self after I have my baby girl. 
Anyone else have these feelings?
