Pre eclampsia ? I don’t think so but curious

Emma

What are the beginning signs of pre eclampsia ? Cause I know pregnant causes u to retain water but this morning my legs were really sore and swollen my ankles not so much just a tad but u can definitely tell my calves aren’t shaped anymore it’s kinda just straight down until u get to my ankles there’s a slight curve. I have an appointment Tuesday and I’ll see if it gets better or worse but being diabetic I’m really nervous this could be the start of something
