I don't want to be that person, but just to correct some important misinformation for some of you peeps planning/avoiding baby making in the future: The ovulation time (the days when you're most fertile and most likely to get pregnant) is some time AFTER your period starts. Trying for a baby during your period or right when it starts will give you the least chance of getting pregnant. If you have a normal monthly period (getting it every four weeks), your ovulation time is normally between 10-14 days after your period STARTS (not when it ends).
