Dear Sharon,
Definitely hormones! Been there, done that and so has my daughter. What you have is called Estrogen dominance, where your body is trying to make up for the nine months of pregnancy by producing more estrogen, when what it really needs is Progerone! I'm not talking the pills that have progestins (that's literally from horse urine!) You can by Progesterone cream at any health food store and many drug stores or online. But make sure the progesterone comes from the wild yam and that each ounce of cream has at least 400mg of progesterone in the ingredients. Read the box, the label, AND the insert to find out how much you need to use each day(normally 1/4 to 1/2 tsp.) You will take a break for a week or two each month from using it to get the estrogen going again (they use the same receptors in your body). Normally, you would start using Progesterone cream on the twelfth day of your menstrual cycle and stop on day 28, but everyone is different (especially if your menstrual cycles have not come back). Just start using it immediately, and you will soon be amazed at the relief it brings! There are several good brands. I usually use Jason or Emerita or "happy PMS" from HR Enterprises (online). Best of everything with your baby and family!
