Blood pressure at home!? 141/91!?

Sunnie • 💗👼🏻💙💗💗

Checked my blood pressure at home because my young sister wanted to see how a blood pressure monitor worked lol. Well I took it and it was 158/86 but I was talking so took it again and it was 148/92 which is still high. Waited 10 minutes and took it again and it was 141/91. I took everyone else’s and no one else’s was high. But I’m not sure how accurate they are. Should I be worried? I’m 28+2. Tia x
