Possibly pregnant.. don’t wanna hurt the baby

I had unprotected sex like two days ago so obviously there’s NO WAY to tell if I’m pregnant now but I am not sure like I feel like it could be a 50/50 considering the circumstances (he came inside me but you never know) however there is a supplement I take which one the label says it’s not recommended for pregnant women but I still wanna keep drinking it bc I need it for the gym so I should be fine to consume it until I know for sure right? And I have a few concerts coming up that I’m going to and I plan on drinking alcohol that should be fine too right? Obviously when I find out I will stop consuming the product and drinking beer but for now I wanna continue my life as I am normally and want to know that if it’ll be fine.. thank you :)
