Blood pressure

I am 32+1 with mo/di boys. I normally have low blood pressure that is around 96/62 with a pulse rate of 98. For the last 2 days my blood pressure has been around 110/78 with a pulse rate of 116. With a horrible headache that seems to never go away. My mom has preeclampsia with me, and Im scared that I might be getting it, has anyone else experienced this?
