I had my regular period last month but it was very light from May 28 through May 31. Then I got spotting really dark brown and really watery only when I wiped down there which last for 5 days. And my period date this month supposed to be June 25. But its June 28 and I still don't have my period. I tested on June 26 which came up as negative. Please advice seriously I am really confused. The spotting that I had 10 days ago could it be implantation bleeding or could it be my regular period?
