Hi, so the day of my expected period I only saw blood when I whipped but during the night and that usually never happens but the next morning I woke up and got up and felt some blood come down and felt a little blood clot come down as well and went to the bathroom to check and my underware was filled with blood and I had very strong cramps, after that barely any blood came down & it continued to bleed and it finished the same day my period would've stopped but it was much lighter then my usual periods.. Could this be implantion bleeding or period?
