I was suppose to start my period two days ago, I had bad cramping and light spotting. I've been spotting for three days now.?

If its possible.... that you may be pregnant ...this could be a symptom...Take a pregnancy test if your symptoms continue for 5-7 days more...On the other hand you may get a heavier period than usual. Consult you GYN is any other symptoms.... Hope this helps Dr Z.
