My last period was on December 7th. But on December 21st me and my boyfriend had unprotected sex around 3pm, he pulled out but the ejaculation was still (if not in) my vaginal area. About 30 minutes to an hour later we had unprotected sex again, this time he ejaculated inside me. After sex I realized I was ovulating. Not really knowing if we were ready to have a kid, the next day I went and purchased plan b one step and took it around 4 pm. About a week after sex I woke up feeling kinda sick and then that night felt a weird butterfly feeling in my stomach. After reading more about plan b one step I discovered a lot of people saying "if you have already ovulated or are ovulating during sex plan b will not do anything." Because plan b is supposed to stop ovulation from taking place. So what's going on? Do you think I'm pregnant?
