HELP CONDOM BROKE

Condom broke what do I do!?

Was having intercourse with my husband and the condom broke and his sperm got inside of me. I got off my period monday and I’m irregular and I’m not on birth control. I weigh a good 230-245lbs and I just took 2 plan b. Is there anything else I should do ? I’m panicking at the moment and don’t know what to do. Im tracking my ovulation now as well. Also when should I take a pregnancy test ?
