My daughter was 6 weeks pregnant, a hard core smoker. She quite and two days later had a miscarriage. After much reading up on the matter many had reported having miscarriages by going cold turkey with smoking. She was even advised to stop slowly but wasn't told why. It's odd that the two days she went cold turkey the following day she started showing signs of spotting. They sent her to the ER where they did a ultrasound. It showed she was 6 weeks along but no heart beat. Needless to say once again i am bitter towards smoking. Why did they tell her to stop slowly?? what do doctor's know that we don't and why they advised her to stop slowly?? i am just so damn mad but i know there is no way of knowing but soo many in forums had reported it
