My last periods were on 23rd april took ipill on 29th april due to unprotected sex though he didn't ejaculated inside me but too just for precaution because chances of pre cum was there, got withdrawal bleeding on 7th may which lasted for 5 days. Today I have light brown discharge similar to white discharge. What does this mean? Is it a sign of periods or something else?. My menstrual cycles are 25 days long I usually get it periods 5 days early according to actual date also took home pregnancy test 3 days ago n that was negative.
