R.A.
I was completely hormonal during my pregnancy. I was easily irritable and so emotional. The littlest thing would upset me and I was so sensitive. I think I went two or three months straight where I cried myself to sleep every night. Then, I would get upset with myself and angry for being so emotional. Then worry that somehow all that would affect my baby.
For me, it just helped to talk to someone about whatever it is that was bothering me. There's an old wives tale that your baby will look like the person who upsets you most during your pregnancy. My son looks like his daddy. :P
