I'm 28w3d and for the last few days have just felt moodier than usual (and moody periods are lasting wayyy longer than the first two trimesters - hours vs minutes, crying for no reason, just feeling generally like not getting out of bed). It's not like me at all to be like this, I've been picking fights with my very supportive husband and I just feel really lonely. It's not constant, I have hours of feeling myself in between these "episodes." Is this a normal hormonal thing? Will it pass? This is my 1st pregnancy and I am afraid to tell my mom or friends about what's going on because I've been so happy and energetic this whole time. Any advice or words of encouragement?
