My AF doesnt start till tomorrow june17, according to glow. But at 1am today june 16, I had went to the bathroom to pee. But when I wiped there was brownish mucus with a bit of blood. I wiped again the toilet paper was damped pinkish, the third time I wiped there was nothing. I went again around 12:30 and there's nothing. Could it have been implantation bleeding or my period? Feel free to comment. Thank you!
