AM I PREGNANT?!?!

So me and my boyfriend had unprotected sex all last week and the day before yesterday and yesterday... my period is5 days late I got a pregnancy test and I’m going to take it in the morning because I’ve been dizzy today, I’ve had headaches the past 2 days, and abdominal pain... I wasn’t really spotting but when I went pee like 2 days ago that’s whole day every time I’d pee the toilet paper would be very faintly pink. I read that it can be spotting from the egg planting in self into the uterus for fertilization and I could be pregnant I’ve also been having diarrhea..
