Hi.... I'm 18yrs old and i just want to find out if what i am going through is Normal. I had my period on the 14th of April and it ended on the 18th. On the 21st of April i slept with my bf....we used a condom..but just to be on the safe side we make sure i use the morning after pill after we've had sex, the unusual thing is tht today is the 27th of April...the same month i had my period,had sex and took the pill....on this very day i have started my cycle again!!!! Is this normal???should i be worried??
