i came up with this chord progression and i havent a clue what it is. clearly it is not a usually mode of the majour scale because the intervals are weird

it goes; D5 B5 F5 Bflat5 A5
D5 B5 F5 Aflat5 A5

sometimes i play C5 after the second line eg D5 B5 Aflat5 A5 C5

if the rythm is useful it is 4 beats of D, 4 of B, 4 of F, 2 of Bflat, 2 of A
4 beats of D, 4 of B, 4 of F, 2 of Aflat, 2 of A

this seems wierd because there are four consecutive notes in a row if i dont use C5 and if i do there are 5. i could be temporarily shifting the key or adding flat fives but i am not sure.
