I wouldn't even bother with the test strips at this point- you know you have proteinuria-- really really significant proteinuria-- so I'd concentrate on watching for symptoms that things are getting worse, and counting your kicks.
I'd especially watch for sudden, severe swelling, or if you all of a sudden stop peeing as much as you normally do. If you're drinking a lot, and not peeing as much as you're drinking in, I'd go to the emergency room. If all of a sudden you get coke-colored pee- that's a trip to the emergency room.
On the other end- you probably should watch for signs that the preeclampsia is becoming more severe- headaches that won't go away with tyleonol, or visual disturbances. These symptoms also warrant a trip to the emergency room.
Are you doing non-stress tests to assess how well baby's doing? In addition to non-stress tests, it's really important to do your kick counts a couple of times a day to make sure baby is dealing with the stress well.
One more thing... what is your baseline blood pressure? THe guidelines for hypertension used to be-- rises of 30/15 from your baseline for hypertension, so it's possible that you do have frank hypertension for you.
I'm really concerned about you. A +3 is a pretty significant amount of protein, and I'd really hope that if a doc sees something like that that they'd keep digging and monitoring until they figure out exactly what it is- a 24 hour urine, blood work, fetal surveillance, even hospital admittance- and to see you soon. A lot can happen in a week. hang in there- watch for changes- and let us know how you're doing, ok?
