Why is one of my female guppies chasing another female guppy?

I have 3 pregnant guppies in my tank at the moment, no males as I accidentally bought all pregnant females from a pet shop. There is one dwarf guppy who seems to just wander off and do stuff by herself but the 2 normal sized guppies hang around each other more (maybe because of size and they are more alike). The most pregnant female who has a black garvid spot and the biggest belly is chasing the other big guppy who's belly isn't as big (not the dwarf because I think she isn't much of a threat to the biggest guppy). Why is she doing this?

    Pregnant fish are stressed, scared, possibly in pain, and very vulnerable. Those thing lead to aggression, defensivness, offensiveness.

      Do you think she could be warning the other fish to stay away from her because she might be about to give birth or something??

    Jealousy maybe?

    When my parents had tropical fish, they had to put the pregnant guppies in a separate 'birthing' tank inside the big tank. As some other fish would gobble up the babies as soon as they 'popped' out!
