Yep, it can. I had pretty much the same symptoms as you, on about day 6 with Darcy. Though my bp was 210/110. I also suffered mild kidney and liver failure, so it's definitely worth taking seriously and keeping an eye on. I had to go on meds for 6 months and still to this day have regular bloods to cjeck function
My doc this time told me it does usually coincide with the milk and is often accompanied by a late onset PUPP rash - which I got on day 9.
Good luck hun, praying it goes down for you.
