4-5 weeks NO SAC

Hello po! Question lang sa mga kagaya ko. (positive PT - Faint line) Nov 11 nagpacheck up ako Trans V - No sac po pero makapal lining ng matres. BED REST required and repeat trans V after 1 week. Nov 19 - Trans V. - Still no sac and baby. Mas kumapal lining ng matres Inulit ko yung PT - positive pa din medjo mas malinaw na yung line. Novemver 22 - Still no sac pero mas kumapal yung lining ng matres. Be back daw on Dec 8 to check. Ayoko po pang hinaan ng loob pero, May chance pa po kaya? :( thank you po
