Swollen cloaca after laying an egg?

[Bekahlands]

I've had my cockatiel Chicken for just over 2 years now. She's never laid an egg until now. I've noticed since she laid her egg (15 or so hours ago) her vent seems to be a little swollen. I'm wondering if it's irritated because she doesn't tend to lay, or if there's the possibility of another one in there? She is acting normal, apart from trying to nest lately. Honestly I'm not sure why she's decided to lay, she doesn't have a mate or anything.

I have to try and get a picture of her vent (she hates phones), but I'm wondering if someone has had something similar, and if I can do anything to help the swelling go down?

She might have another egg in the way , next eggs mostly come 24- 48 hrs

Did she have any trouble with the first egg? Any extended straining or blood?

I didn't see her actually lay the egg, as soon as I woke up the egg was already there. There is no blood on the egg, and the shell looks good.
Poor thing is super cuddly today. I'm gonna keep a close eye on her today incase she lays again.
I got a picture of her last night I've attached
