Dear C.-
Congratulations!! You are nearly there.
That being said, if you have not already, I would look into taking some sort of training. This may be Lamaze, Hypnobirthing, the Bradley method... some type of class or course that can provide you with factual information about birth and the birth process. Each birth is individual but there are certain steps that everyone's body must go through and there are certain telltale signs for each step.
On a site like this, you will get a lot of advice about "doing" labor one way or another. No one way is right and no one way is wrong. You need to find the best fit for you.
For me, I chose the Bradley method. I also birthed in a hospital, although my husband and I considered homebirth as my pregnancies were both "normal" and without complications, and we hired a doula. This last step, hiring a doula, I would recommend to EVERYONE!! I birthed at Valley Hospital in Ridgewood, NJ and they have a program with "in-house" doulas. These same doulas also teach their birthing classes (and I know they run weekend courses so you are not too late yet to catch a class...)
This website provides a good idea of the stages of labor including transition.

I recall from my classes that transition is generally the hardest stage. It has been documented that it is at this point that nearly all women say "I can't do this." With my first delivery, I never expected to utter those words, but I did and I nearly lost my focus when it happened. My husband and I both knew we were getting pretty close to being first time parents at that point and I think we both got momentarily scared! lol!
For me laboring was a very centered and focused activity. I spent a lot of time rocking on my hands and knees. I also responded very poorly to being touched unless I asked for a wet wash cloth. My huband and doula just had to follow my verbal clues - take it off when I cried I was cold, put it on when I cried I was hot. I also asked a lot for counter-pressure which is the palms of my hubby's hands just above my hips, close to my spine, in about my kidney area pushing in and outward at the same time. It helps rotate the hips out and open. (We practiced the positioning a lot in class but did not actually apply it until labor.) I did not respond well to being spoken to unless it was my husband or doula and they had to be close and whisper softly but firmly into my ears. I kept my eyes closed the whole time too. I would visualize opening up like a flower, being wide and open. I would also visualize the ocean, surging in and out - much like my rocking.
You should also find out in class about the signs of oncoming labor - things like increased thirst, reduced appetite, sometimes the runs - all these things are your body making room and opening up.
Lastly, you should learn about interventions, the pros, the cons and how and why certain interventions lead to others. For example, an epi may dull the pain, but it can dull your ability to push too which results in longer labor. It can also reduce and dull your baby's body as well resulting in reduced fetal heart rate/movements. This leads to increased monitoring and if baby is not "tolerating" labor well, then the doctor may get more aggressive with an internal monitoring and then if they do not like the results of that, it can lead to c-section. I state this more as a general "cascade of interventions" and not to scare you. In some cases, these interventions are necessary. However, it should be noted that in general, they are overused and even abused.
Labor and delivery is not scarey. Fear will reduce and restrict your body's natural functions and will cause you to close down, so don't be scared. It is miraculous! It does not need to be chaotic like the movies. There is pain, but the body, if allowed to ramp up with the labor process, can tolerate it. It's not all peaches and cream, but it is managable with the right support and knowledge.
Good luck in choosing the best option for you, your baby and your new family!!
