"had unprotected sex on dec 6 , took ella with in 36 hours. had slight dizziness the day i took it. took it on a full stomach and made sure i ate a little something every two hours. stayed hydrated. i also took dramine for the dizziness. today day two i only have a slight belly ache. much better then plan b.  which tricks your body into thinking it is pregnant and got all pregnancy symptoms. i would say ella worked for me !"
