Welcome to HCM
I can understand your concern for high BP
,it is slightly higher side,in pregnancy
you need a regular check up of Blood pressure is required as Gestational Hypertension
You can reduce salt intake to 2 to 3 gm /day, and take rest and recheck your BP if is persistatly high > 140/90 mm of hg then you may need specific prescription antihypertensive medications which are safe in pregnancy.
It is also advisable to check albumin
If BP remains in normal range you can wait for routine appointment after 2 weeks if BP readings are high you may consult your Gynecologist before that.
Just Take care
