"i took aftera on the 27th of march after having planned unprotected sex with my husband. i didn&#039;t really experience any major side effects other than headaches and cramping here and there for 2 days and then after that it went away. i still haven&#039;t had my period and i&#039;m 3 weeks late. took a pregnancy test a yesterday and it came back negative. i haven&#039;t had any symptoms of pregnancy but it worries me than my period should have come by now and it still hasn&#039;t. i have a doctors appointment set up for this friday hopefully i&#039;m not pregnant."
