August 4th I had like 3 drops of tiny blood in my underwear and then when I wiped it down there not even a day and that was a week before my period, I thought it was implantation bleeding I had some cramps but mild and my period was suppose to come August 10th or 11th because my cycle is 28-29 days always and I never spot in between periods. August 14th I took a pregnancy test because my period had still not come and there was a very very faint line then about 4 hours later I started to get brownish pinkish discharge, the next day August 15th I'm bleeding but not heavy and not light and I have cramps but not as bad as I normally do l usually get very sick. Could I get my period after implantation? Or am I just not pregnant?
