I'm 17 and me and my boyfriend haven't been using protection for the past couple months. I'm 5 days late on my period, I feel exhausted all the time, I've had cramps, headaches, bloating and my boobs were sore like I was about to start my period but nothing ever happened. I've also been feeling kind of nauseous. I took a pregnancy test yesterday and it was negative but everyone's telling me to wait a couple more days and take another. My periods are always normal. I've never been late and I haven't been stressed out at all. But my boyfriends really hoping I'm pregnant and he was making me so excited and I just got so sad when I saw that the test was negative..
