If you truly had postpartum psychosis you probably wouldn't be wondering if you had it. Are you having hallucinations or delusions? Intrusive thoughts are common in PPD and are not a reason to take a baby away. If you have no plans to hurt yourself or others you wont be put in the hospital either. I remember having all of the worries you have now, and none of them came true when I stepped forward and asked for help.

I wish you all the best . If you want to talk privately its ok.
