if you got your period you're prolly not preg and its also unlikely that pregnancy would cause you gain weight this quickly

but if you're unsure you can deff take a test. goodluck!

lay off the sweets! If you ARE pregnant, there's no reason to be gaining ANY weight at this point, let along 2 full pant sizes and probably a cup or two boob wise. Definitely see your doctor as soon as possible. I'm 25wks now and just now 2 sizes up.

since you've been having 'baby making sex' for the past 4 months, take a test. Not all periods are the same, and it could just be a little stress making it 2 days shorter, but it's not a sure sign you ARE pregnant. again, TEST!!

True. You ACTUALLY usually lose weight before you gain it during pregnancy. I think you are eating far too much because you think you are pregnant, therefore your mind is telling you to eat.
Take a test hunny.
