Hi, I have just found out I am approximately seven weeks pregnant. I had a miscarriage (five weeks) about 11 weeks ago, and I am now very worried about this pregnancy. Is it true that at about seven weeks your chances of miscarriage fall dramatically, as i am just latching onto ,misinformation. Also i have not been able to stop smoking, I have cut down to about 5 a day, and i only smoke half a cigarette before putting it out, but I am worried that I am increasing my chances of miscarriage! Please help, this is my first baby.
