Pregnant platy?

[ishfreedman]

I am pretty sure my platy here is pregnant, I would just like a little confirmation. Posting two pictures to show. I bought her a little over a week ago so she could be any number of weeks in.IMG_0301-3.jpgIMG_6199-3.jpg

It looks like a normal sized fish to me. when livebearers get pregnant they get incredibly fat, like they are about to pop. this one just looks
a bit chunky. although on the other hand, if this fish is a female and has recently been in the store tank with males, it might just be in an early stage of pregnancy.
look at the anal fin(the single bottom fin in front of the tail). if it is normal then its a female, if it looks like a stick then its a male.

That's my concern, it's slightly bigger than it was when I bought it, in the belly area. It has other signs of a pregnant female (Darker gravid spot, lighter color than the male) however it's anal fin seems to be a little tighter than it should be. I was quite convinced it was pregnant, now I am merely confused.

If it is not pregnant, and even not female, I am worried I will have a tank now with two males and one female. Which would suck for her.
