Hey, I was on day 13 when I was really drunk and I had a drunk accident where the guy came in me... I took the morning after pI'll about 6 hours later on the accident. I had horrible cramps through the week accident and it's day 28 of my cycle and I started with a pinkish brown and then to dark red brown.... and I barely have cramps.... is this implantation bleeding or is it too late?
