Should I take a pregnancy test??

My boyfriend and I had unprotected sex about 1.5 weeks ago (eve said my chance of pregnancy was 1% and we were reckless) and he came in me. Now lately I've been having weird symptoms that I thought were just from being stressed but I'm getting a weird feeling that I should take a test. Thoughts??

-extremly exhausted

-lightheaded on occasion

-intense cravings

-boobs look rounder

-stuffy nose/allergies

-bloating

-crying at random things

-just had to run to the bathroom to puke out of nowhere

-random nausea

-constipation

-peeing often
