IUD medicine interaction?

Hi everyone

I got the IUD inserted at the end of June and all has been well. I got Liletta, the hormonal IUD. I started taking St John’s Wort for my mood about 2 weeks ago but I misplaced my pills so I forgot to take St Johns since Thursday and I had sex Saturday. My bf came inside of me and I’m super concerned because I read that it can have possible interactions. Any advice? Please
