Dpende po sa condition at term nio mi. Usually kpg nsa 5-8weeks ngkakaroon p po tau ng spotting kung saan naattached ung embryo sa uterus ntin, pero kung ngspotting ka duting your 2nd or 3rd term need mo ipaalam sa ob mo kc di un normal.
if heavy bleeding and may sabay po bang pag cramps sa puson and lower backpain,if yes then consult your OB. but you can also tell your OB na nag spotting kayo just to be sure na you are ok
