TERKEJUT . Faint line in 4-7 days after make love

Mine was a faint line that barely cant see. It was 2 weeks after i had sex and after my "first period" and roughly 1month after my complete miscarriage which was around 4-6weeks. Now i have a healthy 3weeks old baby boy. If u not sure maybe try getting clearblue digital pregnancy test.it will tell u if u are pregnant and roughly how many weeks.scan best be done at 8weeks and above. I too did check after my miscarriage and the pt was negative then after my period i check again and it was a faint line.better u start eating folic acid.
