Oo mama, normal talaga yan! Especially sa second baby, mabilis ang hormones pero ang pregnancy test ay kailangan ng enough hCG levels para magshow ng positive, kaya pwedeng mag-PT ka nang negative pa lang tapos positive na after a few days or even weeks pa. A few of us moms actually experienced na rin yan, one friend took like 5 tests before she got her positive, haha! The best approach is to retest after a few days or mag-consult na lang sa doctor para ma-confirm agad, kasi mas accurate ang blood test at makikita agad nila through that instead of guessing. Fingers crossed for you, sis!
