Im 25yrs old, gave birth naturally to 2 kids, and have been with my fiance over 2yrs. (So no interferrance including others). Im STD free as imm checked yearly. My period is a regular 6 day cycle with 31 days in between. My last period was Jan 11 - Jan 16. I have no cramping or weight loss or anything. My life and habits are are as normal as can be for the past 2yrs and havent changed. Today (Jan 17), about 3hrs after intercorse (he wasnt rough sexually), i noticed i was spotting..... its a light reddish-orange/brown color. I am not on birth control but noticing i am urinating more frequently than usual (about 3x as much as normal)... I need help! Any ideas of what the reasoning could be or causes?
