My period was due about the 27th of last month.. therefore I am now about 10 days late. I have had severe cramps and nausea (which I never have with PMS) and have had several negative home pregnancy tests and one negative blood test on June the 2nd. I feel as though I am pregnant but am getting frustrated as to why nothing is showing. Today I woke to find I have had some light spotting dark red and brown in colour.. Should I expect this as my very late period.. or implantation bleeding?
