Is It Normal To Experience Bloating After Taking An I-pill And Having Unusual Spotting?

Hiii ..I had unprotected sex on 5th after which I had an ipill within 3 hours of unprotected sex . Next day again I had sex but this time protected . 10 -12 days later ...I had kind of periods with very lighter flow for four days . These were just kind of spotting . These periods were early by 14 days as my date due was on 26 . This was very unusual discharge like last days period discharge . Now I am experiencing bloating in my lower belly . Is it normal or a matter of concern ? Please reply fast
