I had intercourse on 24th night and 25th march morning but I had pill on 25th noon itself and I got periods with very light flow like fourth day on 9th april as I had last period on 13th march. And this was stopped as usual after fourth day then I tested negative with home pregnancy test kit on 19th april. But I have not got any normal periods like heavy flow yet. What should I do? Which medicine I should take to get normal periods back? As i had last period on 13th march
