Ay sis, nakaka-anxiety talaga yan lalo na pag negative ang PT pero ang signs mo parang pregnancy symptoms talaga (sore breast, frequent urination, cravings, mood swings, lahat yan familiar sa maraming moms)! Since nag-PT ka na pero negative, baka too early pa lang to detect or possible na iba ang dahilan ng delayed period mo, stress, hormonal changes, or other factors can also delay it, kaya talaga best move mo is to see your OB para ma-check properly and maybe may blood test na magbigay ng clearer answer. When did you take the PT, and was it first morning urine? Sometimes the timing matters, pero ang safest way talaga is mag-consult na para ma-rule out or ma-confirm, at least may peace of mind ka na!
