Are My Guppies And Platy Pregnant?

ive had platys for a while now and they have never become pregnant. after i had cycled my first tropical tank i put 2 of my female platys in it to get it going and i have recently put them back in my coldwater tank but i think my blue mickey mouse is pregnant? i dont know how she could be when she has been kept with another female so im checking to see if she is and if she is how long to go?
heres some photos



also i have 6 female guppies which i am pretty sure they are pregnant and im just wondering how long you think they have to go before they drop? i already have a small tank of about 20 fry from 1 of the females but the rest will be there first pregnancy sorry about the bad quality of the pictures

heres some slightly better pictures of my platy

looks pregnant to me, but also maybe over fed the way the front bumps out.
