Until last week I was, as my wonderful sister-in-law put it, "one of those happy pregnant people." As of probably Wednesday or Thursday of last week I am SO irritable. I hate my job, my husband often irritates the crap out of me, even my dogs are annoying me. I know pregnancy is supposed to make us hormonal messes but I went over eighteen weeks just being happy (with the occasional crying spell). Is there some huge hormonal surge at this point that I don't know about or are people around me just being particularly annoying?
