Very low blood pressure during pregnancy

G🥀🖤

I am 11 weeks. I have a heart condition that causes low blood pressure and I’m no longer on my medicine to keep it elevated. My blood pressure was 80/46 at my last appointment. Has anyone went through this? What’s the best route for delivery? Vaginal or cesarean? I’m obviously nervous the baby isn’t getting adequate blood flow either but my doctor didn’t seem concerned. Thanks.
