Last month (Dec) my period was late and I got super excited only to start my period a week later. (Dec. 7th).. this month I’m now 13 days late, 41 days since my last period. I’m afraid to test because I don’t like disappointment. When should I test? Will I get an accurate result now? I’ve had headaches almost everyday this week, and today I noticed what I assume to be leukorrhea.. no signs of my period in sight! Help!!!
