Symptoms suggest. This may be the case, but not always. Usually time will tel you the answer for sure. Try a home test if your period is one week late and then see what it shows you.
Get a pregnancy test. If you missed a period, get a pregnancy test. It's the only way to know. If it turns out that you're not pregnant after missing your period or if your period comes, then you need to get a birth control method now. Especially if you don't want to be pregnant. Consider an iud or Nexplanon which are implants that you just set and forget.
