I'm 32 weeks pregnant and it's like I have PMS everyday. I am so irritable and constantly snapping/getting annoyed and yelling. I also have a 26 month old son who constantly misbehaves which is what tends to get me started. I wasn't like this before I got pregnant (apart from when I was on my period) and I don't know if it's pregnancy hormones or just the fact my toddler is older now and more hard work. Anyone had bad mood swings and got better after they gave birth or is this the new norm?
