gaining too much weight

The nurse at my last appointment made me feel bad for having gained 19 pounds already. At that point I was 23 weeks pregnant. I am now 28 weeks and about 3 days pregnant and according to my home scale I am weighing 142. I started out at 114 and was 133 at my last appointment. I am 5 foot tall. Am I gaining too much? The nurse told me at my last appointment to lay off the sugar and carbs and eat no fruit whatsoever and for the most part Ive been doing good. I just did my glucose test and I am about to find out the results at my appointment today. Feeling embarrassed about the 28 pounds I've put on so far, even though its all belly. Opinions?
