"i am 31 about 145 lbs and have used it 3 times. twice, when i was on bc but had forgotten a pill during my 20&#039;s and once when i was 30 and not on bc. it worked the 1st 2 times, with mild pms like symptoms and heavier period. the 3rd time, i took it, i had unprotected sex and realized in horror, right after, that i was in my fertile period. i rushed to the pharmacy and took plan b within the hour. with my prior success, i thought i would be ok. i had a bit of spotting a week later, and since one of the prior times i had early spotting, i thought nothing of it, nor of the tender breasts right before my period. only after i was starving, and late did i take a test-i was pregnant. i had pains until i had a termination and a cyst after. condoms."
