My last period was on Oct. 19th and I started to ovulate between oct 31st - Nov 3... However I on nov 9th I started spotting that whole day it was very light but a bright red then on the 10th it turn into a brownish pinkish color and it only went on for a half of day and stopped. On the first day it experienced sum light cramping and now I have bad headaches but no pregnant symthoms. And I took a test on the 10th but it was negative but it was a dollar store test so I might not have been too sensitive to tell. But I haven't had my period yet it's suppose to come on the Nov. 16th but is their a possibility that I can be pregnant and if so what should I do.

SOrry but I am 20 years old I never took any birth control pills
