might be pregnant?

Yani
I'm currently five days late on my period. I'm usually right on time. I feel bloated and like... extra tight (?) deep inside. Idk. I'm kinda freaking out, not spotting or anything. Felt a little nauseous during the weekend but I was also drinking the night before. Also I've been kinda gassier than usual and extra hungry. Don't know if that means much.
How late should I be before I go get a test? I'm so scared!
