emergency contraception
"Had sex on the 7th of August. Took Plan B about 23 hours after from the intercourse. Haven't gotten my period yet because I'm not supposed to be due until the 20th of August but a major side effect that I've been experiencing is a MAJOR amount of tiredness and exhaustion! When I got home from work the day after I took the pill, I went upstairs around 9pm to sleep and woke up the next day around 1pm. I wake up extremely exhausted and my feet start to get tired as well. Also I barely ever hungry anymore... I'm 18 years old so this is very unusual for a teen... Hopefully my period comes soon."
