I am 28, not on birth control, no medications. I got my period right on schedule except it was dark brown. Only enough to fill a pad in an entire day. It was the first day so i didn't think anything of it, but it continued the same on second day. Then it got lighter say a panty liner two- three a day. It's now day 11 with no actual red blood. There when i wipe and some small drops a few times a day. My boobs don't hurt, im not nauseated. I had mild cramps at the beginning, and sometimes off and on.is it implantation bleeding? Maybe something else? Would a test show this early? Technically i don't have a missed period unless this didn't count as one. I feel fine other than the worrying I'm doing now. My periods are always on time, 5-7 days long and heavier in the middle. Any help would be more than appreciated.
