"Take Action vs Plan B"

Hey everyone, so my boyfriend and I were on vacation this weekend and we had sex technically Saturday morning *around 1 or 2 am* and he finished in me. Then the same morning we had sex again and he did it again. I took this emergency contraceptive pill called Take Action (cheaper than Plan B) that afternoon around 5 but when I checked my period tracker it said that I ovulated Friday and the information on the back of the box said "The Pill Does Not Work After Ovulation" should I be nervous? And normally my period tracker is very accurate... PLEASE HELP
