to fat to eat normally?

Shaunamumma

I went to my doctor recently just to let him know that my midwife recomended a glucose check at 28 weeks, He said okay no problem
I was over weight before i got pregnant,  the last time i checked i was a lil over 15 stone (BP)

Then doctor asked me to stand on the scales and it came up that i am 16 stone!
Im 5 foot 11 and i carry my weight well mostly and he told me that i need to be careful etc he told me that iv gained alot of weight recently and that it couldbnt all be due to the pregnancy .. he asked  ''why is this ''? im not sure what he ment.

Because im overweight im so afraid something terrible will happen to my baby! 
can i still eat my normal dinners such as meat veggies and potatoes,  salads, yoghurts, etc? and maybe a few sneaky chocolates? im trying my best to be heathy and i have taken up swimming but i am still so afraid, please help!
