Ay congrats, mama! TVS (transvaginal ultrasound) ay safe na gawin kahit ngayon at 6 weeks, actually yan ang best way to confirm the pregnancy at heartbeat, mas clear siya compared sa regular ultrasound sa ganyang early stage. Tungkol sa mangyayari (spotting/cramping), common lang talaga yan especially first trimester, pero para peace of mind mo at sure na lahat okay, better i-mention mo sa OB mo sa first check-up mo so they can assess properly.
