So I've been TTC for 5 months. Had 4 regular 5 day long periods. This month I bled lightly for 2 days (5th & 6th) then nothing. Today I have noticed brown stringy stuff. All before my period was due I had pregnancy symptoms, sore boobs, nausea, no appetite. I've uploaded a photo of the brown stuff and hoping it may be implantation bleed??? I've done a negative pregnancy test.
