2 questions. 1. are you over weight? 2. are you underweight, with a really high high metabolism hard to gain weight, cold, etc? ok 3 questions......... 3. do you get really nervous about being in a Dr's office?
1. sometimes when over weight just being pg increases your bp due to the increase in work your heart has to do
2. if you are really thin and have trouble gaining, etc. you might have a thyroid problem. sometimes you don't know till you are pg and the first symptom is high BP starting at the beginning of your pregnancy
3. many people get "white coat" high BP. your bp goes up just walking into a dr's office. i know mine often did that with my first pregnancy. i had to do breathing exercises to relax and calm down.
the top number is fine, but the 94 is high. i'd try to concentrate on staying calm etc. don't work out right before an appt, don't show up late running. perhaps go by yourself, without your DD, if she was with your last time. if it's still high your OB will talk to you about it.
