Glow says aunt flow is due today.. I am not testing in till the fourth of she don't flow when I am back home with my SO since I am out of time. Ovia says I'm not due to start in till the fourth anyways. But this morning I had lite brown spotting but its gone already. Could that be implantation bleeding a few days ago I had a tiny spot of blood in my cm when checking and nothing else in till today. The brown spotting was only when I wiped I have no cramps or anything other than heartburn and very sensitive boobs.
