If they was worried about it they would do some testing I had to have it done, I'm borderline my blood pressure has been high it was 140/94 this Thursday so now since its been High the past few times I'm getting induced in Wednesday I'll be 37 weeks tomorrow so he's coming at 37 weeks 4 days. Dont stress your blood pressure is normal.
140or 150 /90 is a sign of preeclampsia
sometimes preeclampsia develops in late pregnancy your doctor will check be sure to mention it it can be deadly
I've noticed that when I go, my blood pressure seems high to me. But my doctor says it's still in a safe zone. When I was in my first few months, I had low blood pressure. Like 90/75. Now it's like 110/85. So I don't know. If my doctor isn't wprried, I'll try not to it just seemed a little weird to me.
You might just be dehydrated.... Drink lots of water! Preeclampsia would have definite signs like high blood pressure and protein in urine.
My thought are worry when your doctor does. Otherwise you'll worry yourself sick lol. That's just from my experience.
