It's a condition that some women get in the second half of pregnancy. It's why they check for protein in your urine and your blood pressure as it's dangerous for the mum. The only way to get rid of it is to deliver the baby, which is why in severe cases women are induced early or rushed for c section. I would ask your doctor for more info because it's important that you have knowledge of conditions that pregnant women and get and their symptoms so that you would know when to seek medical advise.
