11dpo....

So guys, just a quick question, I'm currently about 3 days away from af and last night when I wiped I had the slightest tinge of pink on the tissue, I've had nothing today though, I've been having slight cramps similar to period cramps but not as severe, I feel bloated, I can get really moody, my boobs have been hurting since 6 or 7 dpo, and I've been feeling nauseous on and off for the past 5 days or so, has anyone else experienced this before getting their bfp?
