update on missed period

Ki
Well my period was suppose to come the 18th... that's 10 days as off today... well maybe 4 days ago. Can't remember I thought I started my period and it's not like when you wipe you see it.. idk if any other female to this but when I wipe I wipe really good some days when I feel like my period is bout to come and I don't see when I wipe I stick a finger through there (tmi, with toilet paper on the finger) but anyway I thought that was the start of a period. But my period never came down and that light pink/brownish color was for like a few hours of and on... now it's today and I have some period like cramps lasting for about a few second no longer then 2 mins... I'm confused... I tested and thought I say a vvvfl but that was before the slight bleeding now I'm just scared shitless to test.. and the job I have don't make things better so maybe I missed a period because I have to lift heavy stuff. Idk I'm confused
