Hi Sukina
I was referred to a specialist before I got pregnant with my second child because I wanted to make sure I never had to go through PP again. I wanted to find out if it could be prevented before I even got pregnant again.
My health visitor was very positive about the method recommended by Katharina Dalton (a British gynaecologist and endocrinologist who advocated treating PMS, postnatal depression and puerperal psychosis with natural progesterone). She has written a few books, one of which is called Depression after Childbirth : How to Recognise, Treat, and Prevent Postnatal Depression, it might be worth you reading this.
I had natural progesterone (not the synthetic type you find in the contraceptive pill) within an hour of giving birth and I think for about 6 weeks afterwards. It was a small injection in my leg. It didn't hurt, but I think there are other ways of taking it. I breastfed as normal.
I don't know anyone else that has had this treatment, but I think my health visitor did know of success stories.
I hope this helps. Good luck.
