13weeks pregnant and spotting brownish -red

When I was 12weeks pregnant, I had an episode of serious bleeding one mid night, accompanied with one huge cloth that dropped. Rushed to the hospital and scan showed my baby with a strong heart beat, did a repeat scan a week later still same, baby is very fine.But I have continued spotting since then ,which even increased the 3past days.I have faith in God that I will have this baby, because its after 5years of TTC that I conceived for this..Just want know if any one had similar story and had a healthy baby or have heard of anyone like that.. Thanks For your reply.
