well i had unprotected sex 4 days after ending my period , my bf came in me :( but i took plan b 34 hours after unprotected sex .it's been almost two weeks and till now my breast are itchy and sore. is this normal? could i perhaps be pregnant or are these plan b side effects?

ive been cramping & sometimes i feel like my period is about to start but it's nothing.

my period usually comes till the begginings of the month but these symptoms are unusual!

it's been 12 days since we had sex.

Best answers please i am very anxious to know !
