I am 27yrs old, I only have had sx with my husband. I am still breadtfeeding my 1 1/2 yr old 2 times a day. My periods are always regular, predicable, and similar in consistency. I got my period on time, but instead of being red it has been a thin watery brown consistency for 11 days now. No other pain (other than an 11 day period BEING a pain.) What is going on???
