NEVER HAPPENS!!

Okay girls or shall I say ladies and girls ,

I haven't had my period for 3 almost 4 weeks says the app so a month but I feel like I could've been pregnant before I was supposed to start. I took a test from the 99 but it said negative and for the past 2 weeks I've had really bad pains and the urge to throw up but never actually threw up, some smells make me feel absolutely sick, my feet really hurt, my tummy is hard sometimes and I get full so fast. I even had a banana with ketchup out of nowhere like so random. I really want to be pregnant. I pray everyday. My belly looks pregnant and I can't even stick my tummy in. Please help. I also get many headaches
