Me and my husband have been trying for a few months now. i have a regular period usually lasting 6-7 days.My period this month is a little weird. not sure what i think of it. the first day it started off kind of heavy(bright red blood) throughout the 2nd and 3rd day.I could get away with just using a pantyliner. then it completely stopped that night. i woke up that morning and nothing on my pantyliner. then it came back that late afternoon.(4th day) it was still bright red but just enough to fill a pantyliner. then it stopped again before bed and into the next day, then started back up around the same time(lunch time) (5th day). its a very light pink watery almost color. just spotting. could it be implantation bleeding?period?
