PMS?

PMS, a phrase every woman is familiar with.  But are we really familiar with it in reality?  Before baby, I would last 7 days, and would get a little crampy.  Other than that, that was it.  Now after having my son, I last about 4-7 days but then the REAL PMS started.  Crampy, weak, head aches, SERIOUS mood swings as in angry, irritable, grouchy you name it. Then comes the joint pain, exhaustion, back pain, and feeling bloated, .  Where in the hell did this come from?  It was like a slap to the face, or uterus if you wana say haha.  It was like each month a new symptom popped up.  So not only did baby change my body from the outside, but the inside too?  Not to mention now affecting my relationship because I don't realize my moods until after I have ran my trap. These type of things the books and classes don't tell you. The way I explain it is that your monthly bitch now comes in complete bitch mode! SURPRISE! lovely. . . Welcome to mother hood.
