About a week before my period was due I had very light pink spotting just one day, and then my period was 5 days late (I am always 28 days sometimes earlier but never been late),,,,I was having bad headaches, bloated, and frequent urinating, and now on the 6th day (day after I had sexual intercourse) i woke up with light pink spotting again only when i wiped though, very mild cramps,and then later on in the day it got heavier and darker red and my cramps got worse.. Could it be implantation bleeding, or just because of sex, is it still possible i could be pregnant? I took two tests they were both negative.View Thread
