Doctors appointment

So I’ve went to the doctor he measured my belly and let me listen to my baby heatbeat ,my belly measured at 26 weeks ( like I didn’t know🙄) lol . The last time I went to my appointment I he told me to gain 3 pounds and I told him that wasn’t a problem so to today he said I gained 10 pound lol I told him that was gonna be a problem gaining but he told me to gain 3 more pounds and if I pass over 3 pound he will put me on a diet well just my luck. 🤷🏾‍♀️
