Postpartum flu??

Julie
I gave birth 5 days ago - feel like I'm dying. Shivering, migraine, so dizzy I can't walk, legs feel like cement. We just got home from the hospital today because my son had jaundice. I don't want to go back there but obviously if this is serious I have to. I've read some people feel like this when their milk comes in/wave of hormones. Anyone experienced this? Please someone 😩
