In the past 2 days my male and female convict have been acting differently and im convinced that the female is going to lay eggs soon, heres the behaviour of the male and female listed

.
Female:
Suddenly more colourful
Remarkably plump belly
Red belly
Very territorial of the bottom half of the tank
Male:
The bump he has on his head has noticebly grown a bit
"Flaring" out his fins in the presence of other fish
Saw him digging one of them things the parents bury their fry in
Also very territorial of the bottom half of the tank
Does this seem like the female is pregnant to anyone else?
