My period was 12 days late, and my cramps were minor for about two and a half weeks, I was recieving pregnancy symptoms and yesterday i woke up to pink discharges. A few minutes later it stopped. About an hour later it was blood. It was lighter than my normal period but my cramps became severe where I couldn't even move. Today it's still here but still pretty much lighter than normal, and the cramps not as bad as yesterday. The blood is darker than yesterday .What should I do? Its also not even to fully fill a panty liner.
