Hello, please my menstrual is normally between 30-40 days but sometimes irregular or comes earlier. Had my last 4 periods at date as follows, Dec. 23, Jan 28, March 2 and April 11 Which all lasted 4 or 5 days. Now I had sex march 27 and took 2 emergency pills after 2 hours, and my period came 11 April and ended 15 in the morning. Now am feeling abdominal pain right after my menses but did not feel that during when I was menstruating. Please I'm I pregnant or what is it. Thank you.
