Woops

I had sex with my boyfriend for the first time last night with no condom, however I had been taking the microgynon pill, just not as accurately as I should be. He finished inside me last night and we made sure I took the levonelle morning after pill within 12 hours of unprotected sex. I came off my period on Wednesday and I am due to ovulate tomorrow, can someone settle my nerves? Will I be okay and not get pregnant? Thank you!!!
