I'm pregnant - 15 weeks along. I've noticed I've been crying a fair amount lately. I don't know what sets me off, I don't even know why. I can't even tell if it's a happy cry or a sad cry.... but it's definitely a full on cry. Tears streaming down my face, nose running, loud weird crying noises - the lot! They say it's just pregnancy hormones... but WTF? do I need to cry this much?! Oh and the mood swings. Normally I'm really easy going and not alot phases me, but recently the smallest things are making my blood boil. I tend to notice it and stop myself before I have an outburst at the person to blame, but inside I really just wanna get all kung fu on their ass and release a verbal tornado that will rip their ears off and leave them whimpering in the corner.
