Any tummy trimmer (oral) that is safe for breastfeeding moms?

Yung mommy ko, Biguerlai tea ang gamit dati pa, kaso nga lang, mahirap dahil di mo maeexpect ang bowel movement mo. Pero so far, nag-lose sya ng weight. Pero kung gusto mo mag-focus sa tummy lang talaga, best padin mga exercises like sit ups and planking. :) Eto mommy, 8 ways to flatten your post-pregnancy belly pooch :) https://ph.theasianparent.com/hello-baby-bye-bye-puson/
