I had an I pill last month on the fourth day of intercourse. After few days I experienced vaginal bleeding followed by late menstrual cycle which wasn't normal. My cycle usually lasts for 4 days but it went on for 3 extra days with very less bleeding n more of dark red discharge. Not even 10 days before it stopped n m again on my periods the same way. Do I need to consult a doctor personally. I also feel a regular urge of peeing frequently since then.
