Serum Pregnancy Test

Oo, possible talaga! A few of us had that experience din, sometimes ang hCG levels ay sobrang baba pa sa early days kaya negative pa ang test, pero after a week or more, kumita na enough hormones para ma-detect. I'd say test again after a few more days, or better yet, check with your OB para sure na, they can do a blood test which is more accurate than home tests, especially kung delayed ka na talaga.
