I have just had a BFP 4 days before my AF. If this is right then I am worried due to the fact me and DH have been trying to relax by going out drinking and having the odd ciggy. I now it sounds totally irresponsible but we decided not to run our lives around getting pregnant! Now I think I am (faint BFP, which I have been told would be accurate) I am sooo worried my little miracle willbe affected!!!! What are the chances of a second miscarriage???????
