So AF according to Glow is due the 9th but on Ovia it's due the 6th. Anyways, yesterday I had some left sided abdominal cramping and then just this morning with FMU I had some slight brown when I wiped. Barely anything but noticeable enough. Had some mild mild cramping today later on but no more color after urination. Do you think it could be implantation or early AF? I don't know for sure when I ovulated. Anything is appreciated!
