"took the plan b pill 1 hour after intercourse. i took it on an empty stomach, which you should not do. i felt crazy symptoms for about 1 month. it felt as if i were pregnant. i have been nauseous, tired, mood swings. horrible feeling, and it lasted quite a while. 1 week after i had taken the pill, i got some spotting that lasted 3 days. i took 7 home pregnancy tests (all negative) because of all the worry. but i just received my period today, which i am so happy about.
