Confused...pregnant or period acting up?

Karen

Period was due Oct 5-9 (I vary a few days some times). I saw some pink discharge last night (Oct 8) and thought that was it but woke up and was not bleeding at all. Not bleeding at all today either, planning on taking a test tomorrow morning. I did not experience implantation bleeding with first pregnancy, and have never experienced something like this before with my period. Last month, hubby and I were not really trying but also not using protection all the time...am wondering if I am pregnant or having some irregularity with ny period...what do yall think?
