How fast did everyone gain weight with twins? I'm 14w tomorrow, started at 120ish lbs, and I'm 129 as of this morning. It worries me that only going into my fourth month I've already gained 1/4th of my recommended weight gain. lol (nurse said up to 45lbs, with my singleton, I gained 30)

Did everyone else gain weight faster in the beginning, then have it slow? Or steady the whole time? I gained the most with my first (singleton) in the third trimester.
