Hi, I'm 15 years old and let me just start by saying I know I made a mistake so please, no lectures. On Monday I had unprotected sex with my boyfriend, that makes it one week ago. According to the app on my phone my period is 3 days late. I have had mild cramping until today, I got white discharge & my cramping is heavier. There's also been odor down there so I kind of think its a yeast infection. I've been moody & my appetite has increased, but the sex was only one week ago -- is this a sign of pregnancy? Please help me figure out what's going on with my body!
