I think i have preeclampsia but doctor wont listen.

Is there a test you do to see if you have preeclampsia?

I have super bad headaches, they found +1 protein in my urine and i’ve had blurred vision and my feet literally look like balloons but my OB wont do anything and isn’t taking anything i say seriously because im not having high blood pressure.

EDIT: I haven’t went to l&d because my OB keeps telling me i dont have high blood pressure? my mother had preeclampsia with her pregnancies so im just concerned because i have the symptoms other than high BP
