Positive PT but not detected in TRANSV UTZ

Hi mga mii. Bka may same exp. I went to OB last fri to consult pelvic pain. She advised for urinalysis, papsmear and TransV utz done last SEP18. Nothing seen in my urine test. And normal nman Dn dw ung UTZ, i am expecting my mens nung sep16 onwards so inassume na anytime magkkaron ako. LMP was AUG18. 4days delay na ako. So i took PT and 2 clear lines ang lumabas. Repeated twice, same positive result. My question is, nangyyri ba tlga na hndinsya nkitaa Sa utz bec too early, or may something possible? Nbsa ko na may chance na miscarriage na or ectopic, but i still pray and in high hopes, since nakunan na ako Lastyr. So if God's will na buntis nnga ako, why hndi nakita sa utz? I will gonto my OB na tomorrow, just crowd sourcing if may same ezp dn ba sa inyo. Thanks.
