Same with me momsh. Naka 6 na pregnancy test ako. Lahat positive pero nung unang ultrasound ko, walang makitang kahit sac. Ob advised na magtake ako ng prenatal vitamins and be back 3 weeks after. Pag balik ko kita na si baby. 7 weeks 3 days sya nun and may heartbeat na din. 22 weeks preggy na ko now.
