o.O Okay So here is my story. Im almost 16 if that matters. Last week I had sex 7-6 through 7-8. 7-6 was protected. Other days were not. I Took plan b on friday. But, forgetting i was on antibiotics i thought i was in the clear. My period was suppose to be on 7-10 Last saturday. No period. Now a week later still no period. Plan B says that you can miss your period. But its been a week. My periods are irregular sometimes. But never this late. Now IM having symptoms. For some reason even though i think its too early, Ive been urinating more lately. And if i do not go within 30 seconds I almost pee my pants! Yesterday I went shopping. Halfway through i had to go outside b/c I was feeling like i was going to throw up. This lasted for about 30 minutes to an hour. My stomach was cramping too. I am always tired and i just have an over all feeling of being tired and icky. I feel pregnant.. If thats possible? lol. Ive been bloated. Im hardly ever bloated. Im having a slight discomfort where my uterus is right now. The area around my nipples is like a darker color than normal?? My breasts have been swollen and hurting. And I have only gotten PMS one time in my life... So When Can i test. And what are the chances?
