hello, I had unprotected sex for the first time on June 22nd, my period was suppose to start on July 1st. My last period was on May 31st. my boyfriend claimed he didn t ejaculate but was scared about the pre cum. I took a generic version of plan b the next day. Is there a chance I might be pregnant ? It s July 2nd, maybe I m just paranoid, I don t know. Im very scared. Please answer my questions, thank you.
