Am I pregnant??

in January I didn’t get my period, in February i got it around the 4th to the 10th... I haven’t got my period for March or April but I’ve been spotting lightly on and off for about a week or two (pic included) sometimes it’s even lighter than the pic..

There is no blood in my pee only when I wipe, also i don’t have cramps or any pregnancy symptoms (no throwing up or nausea)

Based on this flow app I’m 43 days late.. could I be pregnant or is my period just becoming lighter??
