If it was really bad I think they would have delivered you already. Im 23+4 and my blood pressure is really high... I will pray that all is well with you and your little one.
Please stay strong and positive darl, i had pre eclampsia at 31 weeks with my first, i ended up having her at 33w 5d. You would have protein in your urine with it too. They do take it very seriously as left uncontrolled it can be dangerous, but if they were truly worried about it the hospital would've kept you in. Just be prepared for it though, but by being in the hospital you'll be in the best hands and they can keep a close eye on you. If bub did need to come early you are far enough along for both of you to be fine.
I'm sorry you have to deal with this! It doesn't sound like much fun at all. Just try to stay positive and take it easy. Only five more weeks to go!
