Is PUMPKIN Pregnant or Not Pregnant?? HELP

[Anikaca77]

all the cats i've cared for in my life...i never accually had a pregnant mom.
i'm so curious to see of she is pregnant.and thank goodness you got her before their born outside,if she is. appreciating you being so caring

Last night I was trying to figure out if she was pregnant or not and it seems that she has a little swollen belly but I could be wrong and she could just be gaining weight....I sorta hope she is in a way because it would be cool to see the birth of kittens but at the same time she is still so little...(with that being said I do understand that there is a world of unwanted kittens, cats, etc. and I've had my fair share in rescueing and putting kittens to sleep because they were covered in magots and I wanted to save Pumpkin) but when I held her up last night you could see the little bump on her sides compared to my other cat who is thin on both sides....well i'll be calling my vet to schedule an appt. to see if she is or isn't...
