Ang LNG sa ultrasound ay normal po, mama! That's the corpus luteum, yung yellow body na nabubuo after ovulation and it produces progesterone to support early pregnancy, so it's actually a good sign. A few of us from our moms' group had the same findings and our OBs were all reassuring about it, kaya relax lang po. It usually disappears on its own by the second or third trimester, pero if you want peace of mind, just bring it up sa next check-up mo with your doctor para masigurado lahat ay okay
