yep, mine has been, so far:

110/75, 120/80, 125/70, 130/70 and today was 135/90

The midwife did a urine test to check for protien, because the bottom number was 90 - test was clear so yay.

She said if the bottom number is 90 or above they'll test for protein to check if its pre-eclampsia or not.

She also said it can go up and down, stay up etc, its only if it goes really high or is combined with the protein that they get concerned.
