super early sign of pregnancy?

i’m either 6 or like 12 DPO, i don’t really know how to count it but i’m one of those. i only have super bad mood swings and my boobs are VEINY. like i’ve never seen veins that blue in my life and usually throughout my whole body, especially my boobs, my veins barely show. when getting ivs they have to like use special tools just to find a vein in me. could this be a sign of pregnancy! i hate to get my hopes up cause i do alllll the time and get a BFN, but a girl can dream.

baby dust to all of you. (me included lol)
