Need graphic details please?

this might sound a little weird but im looking for some VERY detailed info about labor. im 38 weeks(on sunday) im scheduled for a c-section on the 29th. but im having huge labor anxiety. this is my 2nd but i never went into labor with the first, he was 41+ weeks and breech so the just did the section. but 2 weeks ago at the dr they told me this this lil'guy is already head down. now im freaking out that ill go into labor before the section. and i have no idea what to expect!! every thing i read or watch is kinda handled gently. i obviously know the basics but like when the "water breaks" how much comes out and how easy is it to mistake for normal discharge. also what does the mucous plug look like. and how will i know if im having contractions? i've been having terrable cramps in the lower abdoman which i would have mistaken for contraction except the nurse told me i was just dehydrated. im sure if it actually happens ill know it but id really like any insight i can get before hand
