Pregnancy 28 weeks

Went to doctors office done my gluclose test and passed yay! Told the midwife I was still have pain so she did the ultrasound on my cervix and said it looked short. I ask what that ment just said they like it to be longer. My blood pressure was kind of high she said. So she sent me home with a jug to do a 24 hr urine test to see if there was protien in mine. She sent me to OB department at hospital to get monitored for contractions. They only hooked me up for 30 mins no contractions in that time frame. She told me to come back in 1 week.
