Weight gain

So with my first pregnancy I definitely ate for two maybe three and gained 45lbs. I was 320 when I delivered my daughter. This pregnancy my goal is to stay at or under 300lbs I was 279lbs when I found out I was pregnant in august. I lost 15lbs first trimester and as of today 34weeks I'm at 294 so total 15lbs gained. Hoping I can stay under 300lbs so I have less to lose even though I still have over 100lbs to lose. Just wondering how everyone else is doing with weight goals.
