Pregnant??

Guys help!! i had unprotected sex and about 5 days later i started to cramp ( not too bad ) but i woke up the next morning and there was a little blood when i wiped but i never bled again!( i got off my period 1-2 days before i had sex) I feel nauseas almost every morning and sometimes through out the day, i have to pee everytime i take a drink of something and it feels like i’m never full. I would take a pregnancy test but it’s still too early. i actually think it’s too early to even have symptoms but i’m scared! what do you guys think?
