So glad she made it! YAYYYYYY!!!!
Get her in to see your avian vet as an "emergency" appointment in the morning (first thing--ask them to squeeze her in if they must and explain) because they will need to check on her and likely do x-rays---especially since there was bleeding and the egg was stuck for so long---the other eggs (currently internal) could have similar issues --don't wait to get her in there until it happens again (or they may be closed at that time as well). There is a 90+% chance more eggs are on the way. There is a lot a vet can do to help, but it helps if they know ahead of time---they can give hormones, liquid calcium, etc etc (but only a vet can do these things safely).
Eggs are usually laid in clutches (more than one----4 to 8 total- often with 1-2 days in between the next).
Also, watch her butt closely when she poops and see if you notice anything odd (straining, blood, abnormal pink tissue that bulges out when pooping) and tell the vet...AND, make sure that you explain that laying one egg took nearly 2 days, there was blood and it "looked like her insides were coming out"- A prolapse can pop back into the hole temporarily (I don't know whether that is what you saw) but it does need to be checked. Plus, she is likely exhausted and may need some help catching up on hydration etc.
Does she have cuttle-bone in her cage--egg-laying is really hard on their bodies.
Congratulations on surviving the stress---now at least you can get an opinion from her doctor!!! Phew...
OH----and if this egg is fertile, and you don't want chicks, you may have to do something which seems a bit cruel...You have to either replace it with a dummy egg and discard it or boil the egg-like you would a hard-boiled egg, then let it cool (for safety) and return it to the cage--the latter of these two options is most popular and more likely to succeed. If you remove the egg and don't return it, they tend to want to repeat the laying cycle (the longer you wait to decide what you will do while she sits on the egg, the more the chick develops). You have to leave eggs in the cage until the bird loses interest or until the chicks hatch, and chicks are
not straightforward as they seem...Sometimes the parents aren't nice to them, sometimes they need to be hand-fed...and unless you have a bunch of cages for each of them then I would not go that route--when they mature, they will mate with their brothers/sisters and the cycle continues (with the ill health effects of in-breeding).
If she is housed with a male, it could be problematic long-term (for her, and you).
This site shows egg development stages--- you can see that early on, things are developing at an embryonic level, but as time progresses, the chick becomes visible:

Here is what a fertile egg looks like on day 1 of incubation:
