I had my last period the 28 October. I took a pregnant test when i missed my period the 1 are 3 of December and it was negative i waited a few day's and took one more because i still did not start my period yet and it was positive .. thin the 6th of December I started really light brown discharge and that went on for a day and a half to to day's thin that next day every thing was still really light did not even need a pad it has all most stop and that night i had heavy bleeding and some clots for only for hours thin back to the very light spotting and thin i stop all together i took a test during the spotting and it was negative it's not the 9th of dec so i only had spotting 3 to 4 day's i have not took a test yet .I was wondering what the heck was that most of the time i have period's for 5 to 6 day's and mild to medium bleeding... This was not like that at all i never had something like this ..Could this be some kind of implantation bleeding ? when could i take a test if i am pregnant for it to say positive? Is it bad if i am pregnant and i bleed heavy for 4 hours like that ? thank hope to hear from ya ! Gabrielle <3
