Hi Rachk, I would suggest going to the hospital if that's where you're truly comfortable. My experience is just that; mine & I'm not sure where it fits into the statistics of birthing, but I have also had 3 intervention free births even w/out the pit/ oxy, 2 at hospital one at home. Home baby & last hospital baby were also w/ the labial varicosities & my lay midwife & hospital CNM weren't worried at all. I'm not sure if they can even judge if they are internal but 1 ruptured vein likely wouldn't be life threatening & it's something you would notice in time to get it treated at the ER. They'd have to cut you open to suture an internal rupture & of course that's not feasible to do at home. Painful as they are I believe the percentage of veins actually rupturing is rare. I'm pregnant w/ my 4th & I can only tell you that they don't get better w/ subsequent pregnancies but we are planning for another homebirth.
I also have vein issues and they are a pain in the butt! ;) They have never been a concern during labor or delivery although just walking around pregnant with them makes me wonder how I've made it through my last 3 births without popping one! jk Don't be afraid to talk to you midwife about your fears and make the best decision possible for you. There is no shame in having a hospital birth if that is where you will best be able to relax and focus on the job at hand. I've had post bad experiences with doctors and hospitals- none birth related- so I am not comfortable there and that is why I choose home.
