I am still trying to conceive, but my elder sister had high BP during her pregnancy. Her doctor monitored her closely and she delivered a beautiful healthy baby boy. Just follow your doctor's advice carefully and take care.
Yes it can be a bit serious, so don't ignore it, but also don't stress too much because stress will make it go higher! Just have a quick chat with your gynac. They will tell you exactly what precautions to take to keep you and baby safe.
Yes, high BP can be very risky just like high sugar. I had GD so I had to be super careful with both my diet and salt intake to keep everything in control. Please make sure you are eating clean, low-sodium food and constantly staying in touch with your doctor.
High BP is something you absolutely cannot ignore as it can lead to preeclampsia. If your office work is stressful, talk to your HR about working from home or take leave. Prioritize your doctor appointments and get a home BP monitor to track daily.
