Like @lashellg said I think it comes and goes. I definitely wouldn't expect the roller coaster of hormones to completely disappear but for me during the second trimester they subsided for a little while
@fabb004, I'm 27 weeks and it still hasn't got better honestly for me it gets worse. One minute I'm killing him then the next I am in tears, plus the bigger you get the more pain you tend to feel and less sleep you get so that plays a factor in the mood swings.
