Feeling dizzy/dazed after taking prenatals is it normal I have high blood pressure and have had it all my life but today it was very high 157/91?

Concerning. Without knowing how far along you are in your pregnancy, this is harder to answer. I am, however, concerned that your hypertension may be associated with a pregnancy related condition called pre-eclampsia. I would speak to your obstetrician or midwife soon (like today). .
