you sound like me, not only do I not want it looking bad I just cant stand the feeling of it once it starts to get long. I don't know how I have done it for this long but I only have 5 weeks left and I'm not about to give up now!
I go by feel, at first it really wasn't that bad but these last few weeks it has gotten really hard and to me if I have a bush down there its going going to make it harded on me to take care of it after Rylee gets here so I'm still killing my self to shave all the way up until she comes..... so far I havnt had to have help from the man, but I think its getting close to that time.
you could try using a mirror..... or just work on a routine,one side the the other so top to bottom and go by feel.
