Hypertension?

I had Pregnancy induced Hypertension with my first baby. I had him naturally (no induction) at 39w2d. My second was totally fine, I was induced at 40 weeks to avoid the PIH. I’m almost 28 weeks with my 3rd, and I’ve been very sick today. Woke up vomiting, super nauseas all day, horrible headache that won’t go away, and I’m seeing floaters in my eyes. Should I be concerned about high blood pressure? I’m thinking about going to a pharmacy near me and getting it checked to make sure but I’m home alone with my kids and I really feel so weak I don’t know if I have the energy to drive. I have been so fatigued all day.
