Hmmm, must be normal because I was exactly the same early on in the pregnancy.

I cried because there was no cheese and all I wanted was a toasted sandwhich.
I cried because DP wouldnt spend time with me.
I cried because I was bored.
Worst when I cried for no reason!! DP and I would just be sitting on the couch and I'd burst into tears. Or turn to him and start screaming and yelling for no reason because I was mad.

I'm so glad my hormones have settled down a bit! The first 15 weeks were pretty awful for everyone around me!
