I had my last period 11/15/17, which is abnormal and makes me 2.5 months late. I have always been regular (30 day cycle). I took several pee test, which were negative in Dec-Jan. I had a blood test in Jan that was negative as well. I started spotting two days ago (light pink), but still not a normal period. I haven't been stressed or had any major changes with my body. I have been dizzy here and there, but not consistent. Any thoughts?
