I am 17 years old i had sex with my bf about a week ago and another time about 2 weeks before that.On saturday morning i started urinating about every hour and it has not really stopped.I have no pain or burning duringwhen i urinate.My urine is also normal colored.Saturday night i started having some slight bleeding when i wiped.As i recall it was a reddish pinkish.Then on sunday it got a little heavier but still wasnt very much.Way less then my normal periods.On sunday this bleeding became a light pinkish brownish color and there was the same amount as when i started on saturday.My breast also have been feeling somewhat tingly and i have had a slight burning sensation from time to time.I also had slight cramping and a pressure feeling in the bladder and lower abdomen area.I have also been moody and neaseous to certain smells.had more frequent headaches and had a somewhat runny nose more often.Todays monday&the bleeding has stoppd.Did i maybe experience implantation bleeding? PLEASE HELP.
