Am I pregnant?? Worried

Hi ladies.

I've been taking my bc pills for 8 days when this new guy I'm dating and I decided to have sex (I started the bc on the first day of my last period). But the condom broke! So I took plan b one step that very same day. 4 days later, we had sex again (it's a new relationship so we're in the honeymoon stage) and when we checked the condom, it was intact. But I'm still worried...im wondering if taking plan b after that very first time decreased the effectiveness of my usual bc pill? And even though I'm on the pill now, could I have been ovulating because of how new the pill is to me? Maybe some sperms made it in anyways? 😓

It's too early for a pregnancy test so I'm just trying to get some second opinions! Thanks!
