Hi Mary and thanks for your post.
To answer your question in the most direct way possible, the books say that puerperal psychosis affects women between 6 weeks and 6 months after birth. Assuming doctors work to such precise numbers, a woman who started having symptoms 6 months and a day after birth couldn't be diagnosed with the condition.
Unfortunately medical science is rarely that precise and is, like most science, based on averages and ranges. That's just because everyone's different. Humour me here...
To take an example, the average pregnancy is 40 weeks, but it's very rare that people actually give birth on their due date. Much more likely they'll give birth between 37 and 42 weeks. A child could be born at 36 weeks and 6 days and be classed as premature, or at 37 weeks exactly and be classed term.
I suspect the same goes for puerperal psychosis and similar conditions. Reading your list of symptoms, I think we could safely say that if you'd shown them two or three months ago, you'd have been diagnosed with puerperal psychosis instead.
That said, there's a lot of similarities between puerperal psychosis and schizophrenia, and the drugs and other treatments for the two conditions are pretty much the same. Abilify, for example, is used to treat both schizophrenia and puerperal psychosis, so at least your symptoms are being relieved by the right drugs. A quote from www.sign.ac.uk: [quote]Puerperal psychosis should be managed in the same way as psychotic disorders at any other time, but with the additional considerations regarding the use of drug treatments when breast feeding and in pregnancy [/quote]
So, in a nutshell, your psych isn't necessarily wrong; on the other hand 8 months is pretty close to 6 months. But the treatments and care needed are the same for both conditions. I don't know for schizophrenia, but for puerperal psychosis, at least in the UK, the text books say treatment should last a year. Ensure your concerns are listened to - that's probably all you can do until the year's up.
I hope that's helped a little, even though it's kind of an "I don't know" answer. If you like, please let us know how you get on, and best wishes.
