Man mood swings

Any one else's So have a major mood swing before the baby was born? My boyfriend has been so supportive and helpful. He's amazing. But today he just kinda snapped and was super mean for no reason and made me cry and then was mad I was crying. He's just been super off today. I'm five days away from my due date and I can't deal with this right now. Been crying on and off all day because now everything is setting me off.
