New to glow!!!!

Well was suppose to get my period a week ago... I'm 1 week late I have sore breasts my body temp has been higher than usual, I've been experiencing difficulties smelling meats! Also been moody also having lower backaches and slight cramping. Also craving a lot of chocolate. Stomache feels hard and my dog is now starting to lay on my tummy and sniff it. I've been feeling bipolar-ish, mood swings and I took a test 2 days ago and it was a BFN! All though I think I tested too early.. Anyone can give me advice on when to test again?!? Please and thank you ladies!
