i had sex nearly 4 weeks ago. I'm on the pill and i also took the morning after pill but i still feel like i could be pregnant even though I've also taken a test that says I'm not, but i have an ovarian cyst which may of affected to test apparently. I've researched the symptoms of pregnancy and i have some of they symptoms but i do not know if I'm over exaggerating or not. i just need some reassurance really. I'm 17 and im not too sure on what to do..
