.. 18th. I know for sure on June 17th that he pulled out on time but I'm not so sure on the 18th... we didn't use protection at all so I took plan b on the 18th.. Today's June 27 and i didn't get my period yet, I'm worried if I'm pregnant.. This is my first time taking plan b, is it possible that my period can come late because I already had it in the beginning of the month? Is there anything I can do to induce my period?? Pls help
