Gained 9 pounds in a month 🥴

I gained 9 pounds In a MONTH. I just had an appt today and I’m up 9 pounds. I’m 5 months pregnant but I feel like that’s an insane amount to gain! How do I lose some while being pregnant? Just eating better? I definitely haven’t been eating the best but seeing it on the scale

Has me feeling disgusting 🤦‍♀️

Edit to add I’m 5‘10“ , 20w 2d and this is really only the weight I’ve gained since becoming pregnant. I was just worried bc I felt like that was a lot for such a short time. But thank you for the replies. This is also my 3rd baby
