Help! I’m 31+3 & suddenly have high blood pressure!

I went to the doctor at my 31 week visit and my blood pressure was in the 160s over 90. I was admitted to the hospital overnight in labor and delivery and put on blood pressure medicine. I am writing out of work as well. I was given a steroid injections to help the babies lungs mature since he’ll likely be coming by 37 weeks IF I can keep my BP down. The doctor wants me to call every time my blood pressure reaches 160/100 or higher. I’ve been teetering around 130-160 over 90 but a few times spiked to 180/100. Obviously I’m to decrease the sodium but was curious if anyone has any diet/menu ideas for gestational hypertension. I’m open to any other suggestions too. This is all so new to me! Thanks ladies!!❤️
