Ay congrats, mama! At ganyan talaga ang early weeks, kaya common ang weird cramping, spotting, or parang period-like feelings kahit wala pang obvious bump, plus the nausea and exhaustion hit different pa lang with each pregnancy. Buti na lang may scheduled transV na kayo sa May 28, makikita na ninyo ang baby at lahat ng details, pero if anything feels off before that or worried ka sa cramping/bleeding, don't hesitate to contact your OB agad, better safe than sorry talaga. How are you feeling otherwise, nauseous na ba?
