sex/birth control/plan b pill

me and my boyfriend had unprotected sex this saturday. he cummed and it got on my stomach and inner thigh but he was so nervous it might have gotten in my vagina but i’m positive it didn’t.. but we got a plan b pill. i take birth control pills and i’ve taken all the pink colored ones and i’m on the white pills now bc i’m supposed to start my period today (sunday) so i just took my first white pill but i haven’t started my period yet. so i’m sure i’m safe because i took the pill but he’s so nervous bc he’s freaking out until i start my period to just be 100% safe. but also this is my first month on the pill so i’m not so sure if this is also maybe why it’s not an immediate period.

but my questions for this post and for y’all are

1) am i safe now that i took the pill

2) when will be period start or how long until

3) how long does it normally take for your periods to become normal with birth control
