Red wag platy pregnant?

[Platy]

Hey,
So I just got this re wag platy from the store and at home I noticed she was considerably fatter then the others. I was wondering if my platy is pregnant, and if she is, when she will deliver. Do you think she may abort the fry because of the transfer. Any help would definitely appreciated. Pics are below.

Looks like you have two females, if she's been with a male within at least 6 months then yes. She will give birth to 50-100 fry every month for 6-12months. What size tank? I see you have a Molly and they need a 29g. I'd say 2-1 weeks.
