weight loss

im 10w5d pregnant

Wednesday i went to my appointment i was at 161 now i’m down to 158 and steadily losing at least a lb a day. I’m not throwing up but i guess you could say i’m not eating as much and i’ve cut down on pops since becoming pregnant. I gained over 50 lbs with my last pregnancy.

Would it just be me cutting out sodas that causes me to lose weight or could it be something else. I do plan on telling my dr at my appointment that i have a 24 hour urine to do thursday. My BMI is around 30 so i know it’s ok to lose some weight but what is to much weight.

I am not purposely starving myself i do have two meals a day and also snack between meals which i did prior to pregnancy.
