25W5D Too much weight gain

This morning when I weighed myself, I gained 2.5 pound in one day, and 4 pound in one week. This is way too much gain. First it had something to do with the weekend trip. Every time when I'm back from a trip, I always gain a lot of weight. Maybe it's because I tend to sit a lot and then eat junk food. Yesterday was the two year anniversary of our first meeting. We got some ice cream cake for celebration. I had 云南过桥米线 for lunch, and dumplings for supper. After supper, my belly felt very stuffed. I had some trouble breathing. I ate a lot, and then the baby had been growing fast lately. It's time to watch my weight again.I had the blood sugar test last Thursday. I didn't eat anything the previous evening, and had some water during the night. In the morning, I drank the potion at 10:45. When I arrived at the lab, I didn't get tested until 11:00. I hope the result is still accurate. After that I got some beef noodles for lunch. I felt sick the rest of the day. I had a headache, and couldn't concentrate on anything. The pregnancy book said that the sugar test sometimes could cause headache as one side effect. I took one pill of extra strength Tylenol and went to bed. The next day I was OK.I should get into some exercise program again, and then watch my diet. The happy second trimester will be over soon. Time to turn my attention to the baby.
