Discharge with streak of blood

Mga mommies sino po naka-experience sa inyo ng discharge with streak of blood. Currently 14 weeks. Nangyari na ito sa akin last May 8 and showed to OB binigyan nya ako duvadillan and heragest. Had an ultrasound when baby's 13 weeks with good bpm and urinalysis result is check every 2 weeks. Tapos naulit kagabi (May 22) ang spotting. Nakaramdam ako ng mild cramps kagabi and ngayon wala naman na.
