Is my doctor doing his job?

I am 35 weeks pregnant and last wednesday I was admitted to hospital for possible preeclampsia. I had a bunch of blood tests as well as 24 hour urine test. My urine protein was 171, it has to be 300 to be preeclampsia. I was checked in the hospital with 167/112 BP. The doctor put me on medication and after 2 days at the hospital I was sent home on bedrest. My friend who is a nurse came by today and gave me a blood pressure machine to test my BP. I was feeling fine but decided to check it. My BP at 4:00 was 150/98, at 5:30 it was 151/108. I called the doctor and told him. He did not seem concerned about it, he told me to double my medication from 100mg of Lebatalol to 200mg. I took my BP at 6:30 it was 136/107. I was feeling more relaxed for this reading and my husband actually took all my readings and would not tell me what they were till later. He did not want to tell me because he knew it would just make my blood pressure higher. So my doctor's appt is wednesday. Does anyone else think that this is a big deal? I do.
