Most ovoviviparous livebearer females such as mollies can store sperm packets for over a year and they're still be able to use them. The female itself decides wether she's open one or more of her folds of the fallopian tube (uterine tube) and release 1 or more sperm packets to fertilize her egss.
With a long period of absence of a male, the female is still able to become pregnant if she's got stored sperm packets.
Even if another male specimen is chasing her and sticking his gonopodium forward, that doesn't mean that an actual mating has taken place. The female itself will decided wether she allows a male to mate with her or not.
But I would let the fry just grow up and watch how they'll develop.
