Hi there. I am starting my first cycle of ivf soon and im very nervous. Im 23 years old and have been trying for a baby for 3 years. I was told to be able to have ivf i had to quit smoking which i did although i found it very difficult. Ivf is due to begin in about 2 weeks or so and the other day i had a bit of bad news in the family and i had a cigarette. I feel so bad cause im so close to ivf and i was just wandering if this is going to affect my tratment. I did a smoking breathiliser test when i first went for consultation and it was fine but im worried they will do another one and it will pick up the one i had the other day. Do you think it would? I feel like an fool for letting myself down but i got some very bad news within the family and thats why i smoked. Any help or guidance on this would be much appreciated thank you
