morning after pill side effects (yes i hava read thr leaflet 4 times) please help?

two weeks ago i took the morning after pill and about 5 days later I got blood coming out and i wasnt sure if it was my period or not because my period wasnt due for about another 2 weeks. it lasted about 4/5 days and it was bright red in colour, so i am confused... was it my period or just bleeding from the pill??? and then a couple of days later i started getting a few drops of light brown discharge and this has lasted for about 5 days now is this normal? i have also peed a lot during the past days idonf know why, but all i know is that this situation is really stressing me out and that i also have upcoming exams which are rlly important and they are stressing me out too!! can someone please tell me if this is normal and when i should expect my next period and whether that was my period or bleeding caused by thw actual pill
