Contractions & rising BP

Felt lousy & crampy most of yesterday. Started having contractions yesterday afternoon about 3:30pm. Laid down, changed positions, drank water. Still coming & they were about 4-8 min apart. Also about this time, I started to get a headache. Checked my blood pressure & it was a little elevated. I have chronic hypertension which has only within the last few weeks started to spike up. After 7 pm. contractions & headache hadn't gone away so we came to the hospital. I'm still only 2 cm dilated & 50% effaced, but they kept me overnight to do a 24 hour urine & run labs. The contractions have slowed a bit, so not sure if they'll keep me or set an induction date. So uncomfortable & ready to meet our little boy!
