High Blood Pressure in early pregnancy?

Alana
I am 12.5 weeks pregnant with my second child. With my first I developed high blood pressure a few weeks before delivery and it continued for about 4 months post delivery. I am already experiencing high b/p with this pregnancy and am really worried. Just wondering if anyone else has gone through this, or has any recomendations for me:) I seem to lose my breathe just walking up the stairs, or changing over laundry. Previous to my pregnancy I was very active and worked out all the time. I am small framed and normal weight. Thanks for any insite!!
