my period came a week early, which is extremely weird because I am very regular. It was a lot lighter than it normally is between medium to light but mostly light and it lasted 3, days then it was mostly spotting or it would bleed some then stop then start and stopped the middle of the 5th day. I usually have heavy bleeding for 6 days or so so I am very confused... could I be pregnant? I took a pregnancy test that was negative but I think it was to early. I took another one on the day i usually start my period and it was inconclusive...So Im not sure if I could be or not. please help..
