severe PMS after baby?

Did any one else get worsened PMS with in the first 6 months of having a baby? I don't feel like it's PMDD status but I just get more frustrated more easily I cry a little more within the week before my period I'm alooot more crampy and hurting when I have ovulation. I am supposed to start AF on Sunday. Last Sunday at church I was cramping so badly at chruch I had to excuse myself from service and walk around a bit. This will be my 3rd period since I had the baby. He will be 5 months next week.
