I need to lose atleast 20 pounds in the first trimester

Hi Ladies,

I just found out I'm pregnant and I'm super excited. Only problem is I'm really short and very overweight for my height. I was working on loosing weight before ttc but hey life never goes as planned!

For me to be at a healthy weight to carry this pregnancy, l'd need to lose atleast 30 pounds in this first trimester. Does anyone have any experience intentionally loosing weight in their first trimester? Anything I can safely do to loose 10 pounds a month. My diet is pretty clean already.
