We started ttc 5 months ago when i had my arm implant removed. This month I ovulated on cd 29 and then at 6 dpo or cd 34 i started having brown spotting. This spotting is very weird, i have to wear a liner but its a little more than just a drop or two. It has been pinky, brown, and really dark brown. I absolutely wouldn't call it a period, but its now been 8 days of this brown stuff. I still do not expect my period until the 18th. All hcg tests have been negative and it doesnt fit the descriptions of implantation bleeding, as its a little (slightly) more than just wiping and seeing it. I wonder what could be going on?
