Spotting at 9 weeks

I know spotting is normal in pregnancy. I can't help but get nervous though because I have had none until yesterday (9 weeks exactly). It is very light and sporadic, but happened again when I woke up today. I also had different cramping all yesterday. Not unbearable pain, but much sharper than the cramping I'm used to. Has anyone else experienced these symptoms starting at 9 weeks? Would you suggest I see a doctor? I have my first OB-GYN appointment on Feb 1st... But I don't want to write this off as nothing and have it turn out to be something.
