Cycle Day30, no AF

Amber • TTC baby one
So I've been regular since September of this past year and all of a sudden I'm late. I was supposed to starters teddy but I didn't. I feel a few symptoms but nothing major like implantation bleeding or sore boobies (they just really itch) I've got bad nausea every day, exhausted, moody, potty 1&2 a lot more, sleep a lot, and I'm hungry a little more. I have taken 3 pregnancy tests all have been clear blues and 2 were digital. All were negative. I don't know what to think or feel. Best advice??? Ttc baby #1
