Started the pill

t

I just started the pill today and its the first day of my period. I was prescribed birth control to help my periods butttt now my question is, when i read the pamphlet it said that if i take the pill during/or on the first day of my period i am protected from getting pregnant. So myyy question is, i am seeing my boyfriend tomorrow so does that mean i can have unprotected sex without really worrying? Or should i still wait. Thank you ❤️
