Your fertile window includes the day you ovulate and the preceding five days. So, for example, if day 1 is the first day of your period and day 28 is the day before you expect your next period, you'd be fertile on days 10 through 15. (But you're much more likely to get pregnant during the final three days of this window.)
Your body will recover much of the psychological craving, that is, it will stop doing the cravings by 1 to 2 months after you have quit, and then it will be time to taper the pill and the patch.
After you quit smoking, a lot of good things happen to your body very quickly. Within just 20 minutes, your heart rate and blood pressure go down. Within 12 hours, the carbon monoxide levels in your body go back to normal. And within a couple of weeks, your circulation improves and youâre not coughing or wheezing as often. But some pretty unpleasant things happen right away, too.
