Need advice

Hello ladies I need some advice! So I have been in combination BC now for about 17 days. By the middle of next week I will start my placebo pills. Well my boyfriend knows that I am on the pill and he wants to have unprotected sex. I am a little nervous about it because I am always so paranoid and worried about pregnancy! I take my pill everyday at the same time I have not missed a pill yet! Basically what I’m asking is if I decide to have unprotected sex is it safe or should I not do it!

Thanks
