Does Delayed Period And Tiredness Indicate Pregnancy?

Hi am 22years old and have had regular periods for the last 9months. My last period started on the 3rd of march and my cycle is usually 29days long. I havent had a period since and dont know if i would be pregant? I have had cramping like period pains for the last week and feel tired alot more. Today I feel very run down with a cold and very tired. Please could you advise me what to do as I yet havent taken a test.
