I had unprotected sex on October 3rd, and took the plan b pill like 2 hrs after but I weigh 174 and supposedly the pill is not effective if you weigh 175+. Today I took a first response pregnancy test, the 6 days before your missed period and it was negative. My period is due in 6 days so if I don't get it by then I'll be taking another test... Has anyone gotten pregnant even if you took the plan b pill? Or has anyone who weighs 175+ taken it and have or have not gotten pregnant? I'm freaking out!! Lol
