Welcome to the forum billy.
I would place your swordtail at least 2 weeks away from her next drop.
A second observation is that the swordtail may actually be a late developing male. Have a close look at the lower ray on the caudal fin (tail) and the leading ray on the anal fin. Both look to me as if they are thickening, which is a thing that happens before a late bloomer male swordtail starts to grow his sword.
