pregnant?

I had sex like almost a week and two days ago, we used condoms however my period is supposed to come in 5-8 days but yesterday I wiped and saw that I there was a light almost pinkish colour on the tissue so I assumed it was my period and took Advil just to prepare for cramps ... so that happened the oen time inpeed yesterday then afterwards it was normal no blood no nothing and even today I checked it's normal pee...I don't understand what it is I'm 20 and I'm scared 😬
