Really need some help

Ok i was taking trinessa 28 for 3 months. On the third month i started my period on 9/29. It ended on 10/5. When i stopped the pill i was still on the hormonal pills not the sugar ones. My SO and i have had unprotected sex almost everyday since my period ended. I have not had a period since the last one. I have taken three tests all negative. None were taken with first morning urine. Is there a chance i am pregnant or is my cycle off due to stopping my birth control? Please answer and give your thoughts
