Yesterday morning at 9dpo I got a faint positive on a FRER then last night I had very little brown spotting then this morning I had some more bleeding that’s dark dark red/brown. Could this be implantation bleeding or a chemical pregnancy? My period isn’t due for 4 days and it’s never early so I don’t think it’s my period especially since I did get a positive result yesterday. Does anyone have any idea why this could be?
