Could I Be pregnant? How should I get help?

Long sorry short my boyfriend and I have had unprotected sex about 8 times he's been pulling out but cum always get on or around my vagina. He also always lays on top of me and fingers me afterwards.  So for two and a half weeks maybe a few more days I've been having weird stomach pain, I've been feeling a little bloated I guess, I've been needing to use the rest room more, I've thrown up about a week ago, I've felt nauseous for this whole time, and have been so tired for the time period as well. Along with that my period is late by three days so far. I am a nervous reck. My boyfriend knows about all this and is worried as well. Should I take a pregnancy test? Who should I reach out to? Thank you in advance.
