Hey mama, totally normal yan lahat! Ang mild back and tummy pain, sobrang antok, food cravings, at sensitivity sa amoy ay super common sa 6 weeks, yung katawan mo talaga ay nagbabago ng mabilis kaya walang dahilan mag-alala.
About ang heartbeat, mas magiging clear yan sa transvaginal ultrasound kaya good call na mag-attend with your Lipo pag-uwi niya, nakikita talaga siya there at makikita natin ang development ng baby properly. The fact na wala kang severe symptoms ay actually blessing, pero I get it ang worry mo kasi parang di ka hirap, pero honestly yan ang positive sign na all is well so far. Para sa peace of mind talaga, let your OB check you during your appointment, they'll confirm everything and you'll feel so much better once you see that heartbeat on screen. Congratulations ulit, mama!
