JWoww has banned her doctor from telling her how much she weighs.

The former 'Jersey Shore' star is seven-months pregnant with her first child and admits she is very insecure about her body.

She said: ''My legs are much bigger. These are the things no one tells you. You're creating a beautiful baby, but you have thunder thighs.

''Pregnancy sucks. I'm exhausted, my boobs are massive and I've never been this big. I mean it's a blessing, but it's crazy.''

The 28-year-old star has been working out every day in a bid to maintain a healthy weight during her pregnancy and hopes it will help her to bounce back quickly.

She said: ''I'm hoping I won't have much to lose. I've been walking uphill three miles a day on the treadmill and doing 30 to 45 minutes of weights. After, it will be lots of cardio and dieting.''

The brunette beauty is hoping to deliver her daughter naturally and doesn't want an epidural.

She told In Touch magazine: ''Everyone thinks I'm friggin' crazy. But they say it's the most ridiculous pain you'll ever feel, so that could change - quickly.''
