24-hour collection test.

Ugh. Spent all day at triage and I am beyond exhausted! 32 weeks exactly as of today with my first, she is due the 25th of Oct. Blurry vision and heartburn sent me to see the midwifes and while at my appointment they said my blood pressure was high and I needed to be monitored. After running labs and a urine sample they determined I had protein in my urine. I have literally had the smoothest pregnancy up until now and I feel a tad blind-sided as the concern is preeclampsia... Any other momma's out there have to do a 24 hour urine collection test? Does it ever come back as a 'false alarm'? :(
