I had sex on the seventh day of my pill, i didn’t start it on the first day of my period so i had to wait 7 pills to be protected. when i had sex, i was on my 6th but the night of i took my 7th. he did ejaculate in me so 2 days later i took a plan B just incase. 9 days later i had some dark red/brownish spotting heavy in the morning but it went away. now i’m on the first day of my placebos and i’m not experiencing any period symptoms yet. should i be worried?
