: I am 13 weeks pregnant and have experienced bleeding on three seperate occasions. This has been very worrying and stressful for myself and my husband. Each time this has happened we have had a scan and luckily everything has been fine with the baby. No one has actually taken the time to explain what may cause this and if it is common. I have discovered that quite a few of my friends and family members know of someone that this has happened too and on some occasions this has lasted their whole pregnancy!! Has this happened to anyone out there?
