Hi, I'm after some advice please. We've ben ttc for 8 month now. I have on average a 25 day cycle. I've been using clear blue Opk and got my smiley face on day 14. I Started spotting brown discharge (only when I wipe and if I insert a finger on day 25 and again today which is the day my AF is due. I've worked it out and I think I may be 10DPO. Could this be implantation bleed or my body playing tricks on me? Any advice would be great. This is he first time I've had spotting as normally as soon as I start bleeding I am really heavy and it's very painful.
