Platy giving birth

[newbie hob]

I have a platy that i got from my lfs about 2 months ago, she came pregnant, she gave birth to 30 fry, but 6 only survived , lastnight she gave birth again to only one (i was able to see her giving birth, i got him to the fry tank immediatly)
she still has a gravid spot on here right belly, could it be that she gave bith to more than that and they where all eaten, or more will be coming, or is it just the one???

two batch of fry without a male

Get used to it. You'll have more to come

she might have more, as maybe that one fry came early, or the other didn't survive.
