TTC Cycle day 39

Geneva

I’ve always been pretty irregular. The last 2 months I had 29 day cycles. This month I’m on CD 39. So my cycles go from 29 days - 39 days the latest. I had a spot of light pink blood yesterday afternoon when I wiped . I was beyond sure that I was out this month... I wake up today with my huge overnight pad on (Because I’m heavy and it’s like a massacre) but it was DRY , not even a spec of blood. Is there still a chance. I took a pregnancy test a couple days ago. It’s was a faint + , but because it was blue dye I was told not to trust it. HELP ME . I ALSO HAVE 0 symptoms not even the normal pms cramps, which are so severe that I’m vomiting most cycles.
