I was like that my whole pregnancy. I'm pretty sure I read 98% of the birth stories here when I was pregnant with my first. I actually think I over-prepared, and didn't spend enough time studying other stuff. So my suggestion is to also give yourself a set amount of time to read stuff about recovering, swaddling, breastfeeding, read any manuals for your car seat, stroller, baby carriers, etc that you haven't read yet, and don't let yourself only focus on the birth stories.
I felt like there was so much stuff that nobody tells you. Like, for example, I was RAVENOUSLY hungry after I delivered my son, and then I ate as soon as they brought me lunch, maybe 2 hours after I delivered. Well, something about my organs shifting around as my uterus contracted back towards it's pre-pregnancy size, made my stomach freak out. I threw up my entire lunch into the lid of the hospital tray. Take it easy on your stomach for the first few hours. Next time around I think I'm gonna ask for Jamba Juice to tide me over for a while, because it hurt to throw up crispy chicken tenders.
Also, first time I went to the bathroom after delivery, I stood up and on the 8 step walk to the toilet from my hospital bed, I gushed so much blood you'd think someone got stabbed. Totally normal, but I didn't expect it. And the nurse was with me to check how much urine came out into the measurement cup they put under the toilet lid... I overflowed the thing and I couldn't stop peeing. It was thanks to that bag of fluids they gave me before it was time to push. I may actually decline it next time, because that IV in my hand hurt SO BAD. It was bruised for a long time and super sensitive.
I expected my epidural to make me feel nothing. But I had pins and needles all over, from my waist down, the entire time. That never went away until they took it out. I hated it. When it got inserted, they numbed me first and the numbing injection felt like a bee sting but it was over quickly, and the epidural felt like this zing of warm lightning from my back to my left hip. It sometimes takes one or two contractions to kick in, and that was my experience.
And my milk didn't come in until after we left the hospital. I thought mine would come in shortly after delivery. But I was lucky if I could pump 0.1 mL with the breast pump. Their tummies are about the size of a cherry, though, so they won't starve. Study the parts of a breast pump. I was so confused when it was time to take it apart and clean everything after each feeding.
And you may also want to bookmark sites like kellymom.com which is basically the encyclopedia for anything and everything about breastfeeding. That site helped me when I got a plugged milk duct (feels like your boob is bruised, on fire, and no milk comes out) and I went and got some lecithin supplements ($4 at any pharmacy with a supplements section) and within 24 hours it was cleared. I wasted 2 days trying to pump it out, massage it out, nurse it out in so many different positions, and used so many heat packs on it without success.
I remember spending my pregnancy with this obsessive need to know every possible outcome to labor, to somehow feel in control. But ultimately, I wasn't in control of things like my son compressing his umbilical cord 9 hours after my water broke, and not having any amniotic fluid to cushion him, so his heart rate dropped to 60bpm instead of 140... and I just had to go with the flow and try not to panic. He's fine. I'm fine. Everything turned out okay. But there's only so much I could have prepared for, and I regretted not spending more time preparing for things like breastfeeding holds and latching techniques. I guess I kind of expected he would "feed like a champ" as so many people say about their babies, and it would just come naturally to us. So, don't forget the stuff after the birth story too! You'll be just fine.
