Blood pressure

ma

I went in for my OB appt 2 days ago and my blood pressure was really high so my OB was concerned and said he will keep a close eye on it. How can he keep a close eye on it if my next appointment isn’t for another month?? I read online about all the complications that can happen with high blood pressure such as placenta abruption and it freaked me out worried. I have a home blood pressure Monitor and my blood pressure is fine but worried that it’s not accurate 😭😭😑😑😕😕 also I’m 25 weeks today.
