Pregnant or not. Please help!

Mackensie

I've been testing now for about 5 days. Testing all. the. time. I literally can't stop. My period was supposed to come yesterday. No period. Don't even feel like I'm supposed to be on my period. 12DPO. Have been having some pregnancy symptoms. I'm always hungry, I'm always burning up, I've felt nauseous, very light cramps, headaches, acne, etc. I just feel pregnant. I've had 3 positive tests but vvvfl. I've had more negative tests than I have positives. I'm now beginning to think I'm not pregnant just because I can't seem to get more positive tests, I'm including the positive tests I have gotten. I don't know what to do
