Help..

Okay so cycle day 24 25 and 26 have brown and red bleeding. Just enough to fill a thin pad. Started brown spotting then dark red, bright red then done. Cycle days usually 35 40. I never get a period early. Also had very light bleeding at the so called time of ovulation or whatever it might have been. I've been kinda stressed. Not on anything. Have had a baby already but never had this before.
