Hi momsh! At 26 weeks, baby's weight can vary quite a bit depending on genetics and how your pregnancy is going, so it's hard to say if it's "normal" without knowing the exact numbers, best to ask your OB during your next ultrasound, kasi sila ang makikita talaga if baby's growth is on track for you. A few of us moms get a bit worried about this too, pero the doctors have charts for this, at they'll let you know if adjustments need to happen with diet or monitoring. Don't stress too much, anak, but definitely bring it up sa next check-up para may peace of mind ka!
