I'm 21and bedwet and wet occasionally during the day since i was younger. too embarrassed to see a dr. to r/o neurogenic origin. what to expect?

Find a way: Embarrassment is painful and often not necessary. Mostly people don't know how many others are in the same situation or even worse. Medical pros are so accustomed to dealing with problems that they almost never are judgemental or shocked. Especially if this can be corrected, it makes sense to just dive in and do it. Perhaps a female dr - you can ask. Maybe that will help. Hope it goes well.
