Hey im 19 and the same thing happened to me. I had a missed period (about 3 weeks) and i was always nauseous and had terrible headaches. I finally got the courage to take a pregnancy test and im pregnant. I took about 4 tests actually and they all kept saying positive. If you had unprotected sex chances are your probaby pregnant ! Good luck !
If you had unprotected sex yes good chance, but only way to k ow for sure is to take a home pregnancy test.
Could I be pregnant with a missed period of 2w
