I had HBP during my first pregnancy and still managed to deliver naturally. It really depends on yourself and on your gynae - I opted for epidural for pain management before my gynae ascertained my decision. She said my pain might cause my bp to shoot up during labour haha.
Now that I am on my second pregnancy, my same gynae put me on low-dose Aspirin after my first trimester, but to stop just 4 weeks before EDD. I have been monitoring my BP readings and it is now within normal range with the help of Aspirin. You might want to check with your gynae of this option, only if you are comfortable.
Of course, at the end of the day, what matters most, is that both mummy and baby are safe, whichever the delivery mode. You can have a preference but rmb to stay open to your other options :) All the best mummy!
