I was admitted to hospital last week due to a complication with my diabetes (type 1) after becoming ill. They mentioned a few times that my heart rate was quite fast.
I saw the midwife on Saturday who mentioned if I had sudden swelling in my hands, feet or face this could be a sign of high blood pressure and to keep an eye out for it. I've come home from work and both ankles are really swollen, I can't remember what the midwife said I should do if this happens 
Is it serious? Should I call the pregnancy advice line or wait until tomorrow to speak to my midwife?
