"took this 12 hours after thr bf ejaculated in me on day 15 of my cycle...one of my most fertile days.....the day i took it the cramps got so bad i almost vimitted, i got so dizzy and weak from it.by the next day i was fine. i wouldn&#039;t recommend this torture...then four days later my breasts became sore....and i have been getting every pregnancy or pms symptom  since (sore breasts, cramping, upset stomach, nausea, lower backache, headaches)....i am due to start sat 4/30.....i took a prego test and came back negative.....this is the longest pms and worst symptoms i have ever had. i think i would have rather taken my chances."
