Only 5 weeks and gained already

KP • Mama of two DD 04/14 and DS 03/16. #3 and last due 3/19
So this is my second pregnancy. With my first I gained 42 pounds and I had just gotten to my goal weight a week before we conceived lol. I had dd april of last year. I have already gained 3 to 4 pounds since then. I haven't been that great with eating so not surprised I gained but that much already is depressing. Didn't help that I ate lots of pizza and cheesy bread tonight l. My goal is starting tomorrow to really watch my calories. Anyone else already gaining fast?
