Anyone been told they have gestantional hypertension?

Heather

Thursday was a scary day, went to see my midwife and my blood pressure was 150/100, sent to the delivery ward at the hospital and they monitored baby and I overnight. Luckily my blood pressure came down on it's own and stayed down overnight. They've now classed me as 'high risk', having gestantional hypertension and said it's more than likely caused by me only having 1 kidney. Anyone else been diagnosed with GH? I'm 26 1/2 weeks :(
