Hi and thanks for using the forum.
The only way to know for sure if you are pregnant or not is to take a test. You can take a home test or ask your doctor for a blood test - both are accurate. Since your period has not been normal for you, I think you should take a test just to be sure. There are other possible causes for an irregular period including a hormonal issue, thyroid problem, sudden weight gain or loss, among others. So if the test is negative, then you still need to see your doctor to figure out if anything is going on. Good luck.
