Do you know how many days our cycle is? ie 28 days?

If so, you should ovulate on day 14 of your cycle. But it all depends on how long your cycle is.

The MAP is safe to take during Breastfeeding but be sure to mention it to the Pharmacist.

If you don't want to use protection or a contraceptive, than track your cycle. I've used this method for the past 2 years.

You have to be pretty pedantic though. I save everything in my phone calendar. The day I get my period. The day I think I'm ovulating and the day my next period is due. Then I avoid sex around the time of ovulation.

I find it as a reliable method if you can remember to follow the regime.
