Welcome to healthcaremagic.
Ovulation - release of egg from ovaries usually happen 10-14 days after start of your periods. Since you've just finished your menstrual period, it is highly unlikely that there is an egg - ovum currently.
Based on the facts about your last menstrual period and your decision to take morning-after pill, it is very unlikely to get pregnancy
Hope my reply was reassuring.
