Panic attacks - help

Bethany • I'm 23, married almost 3 years ♡12.12.14♡ and this will be our second! Our first was born 6.22.16 on my birthday. My second time using this app. 👪
I am 16weeks and 5days. Is it normal to have random moments where you feel like your blood pressure raisers, a lot of shortness of breath and panicked feelings? My doctor said my blood pressure is fine but I have my doubts on that sometimes. It worries me when I get like this.
