Postpartum High blood pressure pls read

Thlyaa

What does this mean? I never had hbp before in any of my pregnancies. I just had a baby a week ago & for some reason my blood pressure has been in the 135-154 & I was at the hospital for a few days I got magnesium drip & got sent home after that & got prescribed Nifidipine. I looked up my results what does this mean? I still feel a little crappy even though I’m taking the medication. Is that normal? I think I have a spinal headache too. I read spinal headaches can cause hbp?
