A little background: my periods are HORRIBLE, they usually start with a vengeance and are heavy and ridiculous until it's completely done & can last anywhere from a week to 3 months... (it's crap) .... anyways, I'm round about 10 to 13 ish days past ovulation and my af is due on Tuesday. I started cramping Thursday, and began spotting this morning (light brown and pink, light flow only whenever I wiped) and then 1 tampon of red, brown, and pink. Usually af is clotty and ridiculous and it's actually a low enough flow that I'm not using a tampon right now..... it's never ever this low of a flow.

Could this be implantation or just the best beginning to af ever? Has anyone else experienced this and ended up being pregnant?
