When Should Be Action Emergency Contraceptive Pill Be Taken After Intercourse?

Hi, I have a question about my recent unprotected sexual activities and using Take Action emergency contraceptive. I had unprotected sexual intercourse on Sunday, March 15th around 4am. I then took Take Action on Wednesday March 18th around 8am. I began a medium period Yesterday morning. I am just a bit concerned because my partner and I had intercourse this past weekend on Saturday March 21st. We used a condom but during the second time in the same night we didn t use a condom. He pulled out and ejaculated after pulling out. This happened Saturday night around 12/1am. Since today is Tuesday and I am on a light-medium period, which is most likely a result from taking Take Action last week, should I be concerned? Should I take the pill again before the 72hrs is almost here? I m worried that there could have possibly been precum. Suggestions? Thank you.
