Pregnancy Mood Swings

So far this week I have decided that I am definitely getting more moody. There have been several things that have happened over the last couple of days that I have just about lost my mind. What I can't figure out is if I am overreacting or if a normal person would still be agitated about what I was. The more things happen the more I think it is me. For instance, on Wednesday I went to get my my blood drawn. I showed up at 8:19 and there were 4 people in front of me. Now I must remind you that I had to fast to do the blood work so I am hungry to begin with. At 8:40 I went up and asked how long the wait was going to be and she said rudely that she was the only one there. I asked again how long the wait was because lets be frank I didn't care that she was the only one there I just wanted to know how long until I could eat again. She told me 15 minutes. at 9:05 I called my doctor and asked if I needed to do the test that day because I know they wanted the results before my next visit which is next Wednesday. She said I could wait until today if I wanted. To make a long story short I left with 3 people in front of me. Today I went to get my blood drawn and I went to a different location because I didn't want to do deal with that again. I got to the lab place at 8am. Unfortunately I didn't look at the time they opened and they opened up at 8:30am. No problem I can handle that I was the first one there. Then more cars pulled up and when it was all said and down there were 4 of us. No problem I thought... everyone knows I was the first one here so I should be first on the list right? WRONG!! One man got out of his car and stood by the door and man number two got out after me but stood closer to the door than me so when the nurse opened up the door the two men rushed inside and signed in before me. I was thinking to myself (and then to the nurse later) REALLY?? Chivalry must be dead. Lets recap.. first one there, female, pregnant, and to top it all off I was wearing Sam's Marine Corp shirt. All I have to say it what is with people these days. Needless to say I almost said something but decided against it. See I am growing up. Although looking back I kind of wish I did say something. Just because maybe they need someone to remind them that they are not all they think they are.
In general I am feeling myself get very short tempered. I am becoming very childlike when I get tired as well. At least I am feeling this and I know that has to count for something. Poor Sam I blame him. Doesn't every pregnant wife blame their spouse??
