Pregnant or just gravid?

S I've has this molly for 8 months now, she's grown to be fairly small but she probably hasn't finished, she's always had a faint dark spot near her abdomen but she now seems to have an intensely dark spot, I have 1 black male molly in the tank with her and 2 other females, but I haven't seen them close to each other for a while, will I be a grandparent or is she just maturing?

this is my male.

This is the female hope you can see her clear enough to work it out by my camera is awful
