Sayang, first thing, please discuss this dengan your OB/GYN specifically, okay? They know your medical history best and can guide you properly on what's safe for labour.
But honestly, many of us mums with hypertension managed normal delivery, it really depends on how well-controlled your BP is during pregnancy and closer to labour. One of my mum friends had the same worry, tapi her doc monitored her closely throughout and she delivered normally without issues. The key is keeping those regular check-ups and being honest about any symptoms like headaches or dizziness. Your doctor might just want extra monitoring during labour itself, which is totally manageable. You've got this!
