Take action pill

Has anyone tried the take action pill? Did it work for you or did you still get pregnant. I took it on the third day literally like a few hrs before it would be too late🤦🏽‍♀️. I found out I was pregnant at 3 weeks and 3 days with my previous pregnancy. I have been having bad headaches, cramps here and there and I have nausea, I feel like I have to throw up every time I eat. I don’t know if I’m just paranoid and scared or what. I want to take a test but i think it’s too early lol. It has only been two weeks and 5 or 6 days.
