i'm in a fix. I got my period this month on the 4th of April and i usually bleed for about 5 days. I had unprotected sex on the 13th of May , after which i took Norlevo. I did not experience any nausea. But however since the 18th of April i have noticed some heavy spotting. what could the reason be? i'm terribly worried. should i consult a doctor?
