CAN I TEST NOW???

Me and my SO had unprotected 2x last week and both times I got a take action pill. We had sex 1 day apart. I looked on google and a site said I had a higher chance at getting preggo with the second pill because it was so close to the first one. My period should have happened yesterday and I'm little nervous. The box for the take action said wait 7 days to determine pregnancy, but I'm nervous rn. I wanted to know if even though I had sex last week could a test pick be accurate this soon?....... (p.s. I'm pretty sure he came in me the second time)......PLEASE NO MEAN COMMENTS, I REALLY NEED ADVICE...
