Almost 2 weeks delayed

Hello mommies, help pls. Supposed to be December 20-21 ako magkkaroon nag PT na ako before and negative pero may isang may faint line. But night of December 30 sumakit tyan ko then akala ko mens lang puro clot yung lumalabas and not feels like mens na ramdam ko. Kinabukasan may lumabas na ganyan sakin para sya meat hindi sya dugo na nadudurog kapag hinawakan. Nasakit din balakang at tyan ko. Nag pa check up agad ako and for trans v daw ako. May nakaexperience po ba sainyo ng ganito? Miscarriage kaya? :(
