Concern for pregnancy scare

Kaydance

My period is about 1 week and 4 days late but I have been having early period symptoms before I was supposed to start on the 11th of this month. I took 3 of the Equate one step 88 cent pregnancy tests that you get from walmart and all three of them showed positive. I took all three in one sitting, is there any chance that I could still have my period this month? A side note, No I have not used protection my past few times having intercourse with my significant other.
