Am i pregnant?

Angela
I took one round of the depo and stopped taking any birth control. I had no periods while on the depo but this app correctly kept track or when my periods should be. My bf fully came inside of me one day. The next day i was extremely horny. I believe i was ovulating as im never horny like that. Well my period should be 4 days late now. I ovulated 2 weeks ago. I took a clear blue test this morning with my first morning pee and it came up negative but still no period. Is it possible to ovulate and then still not have a period and not be pregnant? Is it possible i am pregnant and its just too early to test even though my period should have started on the 9th? Im worried and confused and also scared to get excited just to be disappointed and find out im not. Opinions??
