Cigarettes while TTC

I'm not a smoker. I dont buy packs, im a moocher. I have one everyday or every other day during the work week.

I just miscarried last month and have been trying to conceive for almost two years. It was the first time ive ever been pregnant, im 26, married 5 yrs.

I take all my vitiams to the extreme and barley even drink my wine during the weekends anymore.

Do you think I am hurting my chances to conceive by casually indulging in a cigarette?

I've been trying so long, its hard to give up everything....

Thank you for your thoughts.
