implanation bleeding is usually just a lil spotting or light flow of pink or brown discharge or blood. not like a menstrual cycle. also cramping is usually light to moderate but not usually severe. everyone is different though so take a test to assure yourself if it'll make you feel better.
No, implantation bleeding is very little pink - brown blood.. usually just spotting
Heavy bleeding and really bad cramping is either, your period or a possible miscarriage...
if you're concerned yhou could always go see a Dr... good luck
