Mag 6 weeks pregnant, nag spotting

Kanina nag spotting ako, konti lang naman, color light brown. Bothered ako kasi nung nagpa ultrasound ako, 2 gestatioal sacs ung nakita. Yung isa malaki, yung isa maliit. Sabi ng OBGYNE ko possible twin pregnancy. Due ako for another ultrasound bukas para malaman. Prone to subchorionic haemorrhage. Please help mommies. First pregnancy ko to.
