My Heart Rate is 96bpm ...My nipps hurt like hell..and Ive been getting more sleep than normal...since I woke up at 9am I've been to the restroom almost 8 time... Today I'm supposed to start my cycle.. But the blood I'm getting is SUPER light... And my normal cycle is really heavy.. So the question if the day is... Is this my Period or my Implantation? And should I take a pregnancy test?
