How much weight did you gain with your second pregnancy?

First pregnancy I gained about 70 pounds, I had a lot of complications that caused weight gain and was bed bound. I lost 100 pounds since then and am really loving my body, fiancé and I keep talking about having another within a few years (2020-2021). I’m going to stick to low carb next pregnancy and hope to gain the normal amount, how much did you gain your second pregnancy? Was it harder to come off?
