Got period twice last month. In my body?

On 9th of March I got my period and it ended on 13th of March. The very next week I had to have the emergency contraceptive pill (i-Pill) twice (in the gap of 2 days) as a precaution after intercourse. I got period again on 23rd of that month. It lasted for 3 days. There was no other discomfort. Like no severe pain or anything. Except the normal cramps that happen during every period. This month, I haven't got my period yet. I am not sure when it will come since I got period twice last month, I can't track it properly now. I have been getting slight lower stomach cramps for past one week. There was also spotting (brownish red color) yesterday. Also, I have been experiencing jaw line acne for past 2-3 months. I can't figure out what's going in my body. Please help. Am I pregnant or is it any hormonal issues/changes that's happening in my body?
