Emergency Contraceptive!!!

Alright y'all. So last night I had to take "Aftera" because CVS was out of Plan B and this is basically the next best thing to it was $40. So my situation wasn't really bad at all honestly I was just freaking out at the time. I took the pill within the hour it happened. My boyfriend and I were having sex with a condom and when he went to put it in I guess the condom became dry and I felt it break it had a very small whole he didn't cum or anything plus he wasn't deep inside me he was barely in. So as soon as I felt that I pushed him away SO fast. Within the next hour I made him go to CVS and get me an emergency contraceptive and they didn't have plan B so he opted out to get Aftera. Have any of you ladies tried Aftera? Do you think given my ridiculous situation that I'm freaking out for no reason & that I'll be fine? Sorry guys I'm just freaking out and need some support, thank you!
