Hi, I’m only 16!and starting to believe I’m pregnant. My period has always been weird. But I’ve never missed this much time. I was supposed to get my period on the 20th. I use the pull out method (I know I’m pretty stupid for that) but There’s also a chance it’s just late bc of stress. Ive been terribly stressed, I also had the stomach flu when I was supposed to be ovulating. What do you all think?? Should I wait a few more days? (I show no symptoms of pregnancy and haven’t had sex in weeks)
