Stupid question!

I'm 3 days late, going on 4 (I've never been more than 3 days late before) my boobs are tender, nausea. Super fricken hungry. The right side of my stumuch have been hurting as well as just some random abnormal cramps all over the lower part of my stumuch. Crazy sex drive.. and also.. my dog has been humping me. 😂😂 I know that sounds silly, but is that a sign? I want to wait until I'm good and late before I test, as previously I've tested and AF came soon after. The most I've ever been late is 3 days. And I'm going on 4... so I'm not sure. I'll be testing Friday of no AF. Thanks ladies!
