Can someone tell me what's wrong?

Bl
For nearly 3 days I've had this lightning bolt sensation that goes from the right side of my neck, to jaw and sometimes right nostril. I feel like I have a cold too, just feel weak, bad headaches, and dizzy. Last week I noticed a spot of blood when I wiped as of today I'm 10dpo. Does this stuff happen in early pregnancy (especially the lightning bolt sensation)?
