I did too with my last pregnancy. I talked to my husband about it and it really helped. It was probably just the fact that u know u r gaining weight. not meaning to sound rude. That was my problem. Plus I was being lazy, throwing up all the time, eating all the times I wasn't throwing up, peeing myself, had extreme constipation, with the extreme hormone changes. It can really play tricks on your brain even if you don't have all those symptoms, your hormones will really mess with you.
