Weird Period Craving...

I have been an on and off smoker through most of my teen and adult years. Most of it off but it's always been something I struggle with. Since I found out I was pregnant with my daughter I have only slipped up a couple times and for short periods of time, and she is now 5. Does anyone else (non-smoker or ex-smokers) crave cigarettes when they are PMSing or on their period?
