4 weeks spotting

Hi Mommies :) I'm 4 weeks pregnant po and since November 1 till now spotting po ako, nagpa check up po ako sa OB nag resita po cia ng gamot Duphaston, Folic at Calcuimade . Normal lang ba ung spotting po? Kasi one month na po ito, wala namang binanggit ung OB na kahit ano pinainom nia lqng ung resita nia 2x a day. Pa help po :) #firstbaby #1stimemom #pregnancy #advicepls
