Bc pack started late and unprotected?

Hi all,

As you can read by the title I started my birth control pack for this month late. I was supposed to start it on Sunday, December 29th but couldn’t start it until the next day which was Monday, December 30th (I doubled up on my pills taking Sunday + Monday’s on Monday)

However, I just had (Jan 5th) unprotected sex with my boyfriend in which he finished inside of me. We totally forgot about the risk and are now worried that my bc may not be in full effect since I started it a day late and I may need to take Plan B or a Emergency contraceptive tomorrow. Should I do this for extra precaution? Just really worried :(

**I take Junel-Fe 1/20 which is a combination pill and have been on it for 3 years**
