am i pregnant?

hello, i'm 16F and i had unprotected sex (though pullout was used and we're both sure nothing was left inside) one and a half to two weeks ago, now i'm getting pms symptoms a bit more intense than usual.

my last period was around end-ish of april to the first week of may (around this time last month), and i usually have irregular cycles. we had the intercourse about may 28, and i would say i had stickier discharge around that time (maybe caused by my physical attraction to him?) and we're sure nothing of his ejaculation was left inside me.

now, i barely have any discharge, and are getting pms symptoms. i'm planning to take a test this weekend or the next, am i anxious/overthinking?
