Lol don't worry about it... hormones come with the territory. My hubby and I used to disagree and have these spirited discussions about how to do things... now I just curl up and want to cry. So not my normal personality haha. Just gotta go with the flow. I have used the "don't mind me... hormones" excuse more than I can count!
Yes, it could be hormonally related. I was happiest when I was busy during my pregnancy. I would get out and doing something every day. Do you work? That really helps distract us and keep the hormonal outbursts at bay. good luck dear
