I had sex last night and started my birthcontrol 7 days after my period and missed some doses. he ejaculated on my vagina but not in it and i did not know till 2 minutes after. It says i am 2 day into my fertile window as of yesterday but since i’m on birthcontrol i’m not too sure. I went and took plan B but i am still worried. Is there a chance i can get pregnant? or am i covered since i took plan b soon after the incident happened. Does plan B work when taken during fertile window?
