Pregnant or not pregnant?

Two months ago I was 10 days late for my period. I have not taken my birth control in 3 months so it wasn’t weird to be late. I did however wind up getting my period (10 days later than expected) a normal period. This month I was feeling a bit off; extra emotional, peeing a lot and my period was very short. I took 4 pregnancy test, 2 had positive results and 2 had negative results. I am a bit confused on whats going on here, not sure if I am pregnant or if I am not.
