IB...or... AF!?!

Today I'm 11 dpo and 3 days from af.. around 2 pm I went to pee wiped had blood strikes in clear cm... drove 5 hours with a pantie liner on may of have 3 drops of pink cm it's 1145pm and still just getting pink cm when I wipe... my periods are regular but when I start I start full blown no spotting and normally the first 2 days of my af is heavy with clotting... I have a tampon in to sleep so I guess I'll know if it's af in the morning but what do yall ladies think it is?
