Terrified of birth yet alone getting a C-Section

I’m currently 34 weeks and 2 days . This is my first pregnancy and so far with baby boy . I was diagnosed with high blood

Pressure (on meds to keep it under control) I currently go in weekly for stress test and sonograms. (Consider high risk now) Was called last week to go into labor delivery due to my sonogram showing the cord levels to be high and wanted to make sure baby boy was getting enough oxygen . So far we have been passing the stress test BUT being hooked up to the monitor normally take 20-30 mins but baby boy doesn’t get as high as they want so it takes as a hour plus to finally get what the nurses want to see . I also was told my uterus is still tilted . They haven’t said anything about doing a c-section they just say if he seems stressed at any point they will take him . My question is based on high blood pressure , issues with the cord and oxygen and tilted uterus . Could this affect me from having a vaginal birth .? Should I start preparing my mind mentally.!
