9 DPO, light cramps, light spotting

Crunchy
I am 9 DPO today with af due the 22nd. Last night I had a few sharp twinges and then there was a tint of pink on the toilet paper about 20-30 minutes later. I woke up this morning with a bit more pink but it wipes away completely with tissue. Before af my spotting is always brown brown and comes the day before. Could it be? Maybe I'm obsessing!
