2 days late AF dye 4/1 . What do you think help please

Katerria
So on Monday I took a equate Walmart test which had two in there and it came out negative on Wednesday I took the second in the box and received a faint positive (I know blue dyes have a bad rep ) everyone could see it except 4 people . I could see it in person and it showed up before 2minutes(pic below ) . So I waited a day and retested and if course I received a negative 😒 But my period is two days late which never happens no matter how stressed or how bad I wanna be pregnant . Saturday i was cramping so bad and felt like my cycle had came on so went to the rest room and it was only yellow tinged discharge that looks like boggers I guess . So I'm completely lost what should I do ?? I know if it doesn't come Monday go to dr but my mind is racing
