af late 6 days

AF was supposed to come on 10/16 but didn't. I usually get very sore boobs a week before, that didnt happen, and they still don't hurt. just my nips feel weird and my boob feels like its burning every once in a while. but seriously? I'm not stressed or anything. I took a test couple days ago and it was negative but I've read some women it takes a bit. I've had 2 ectopics and lost a tube. so I'm very very scared....ugh. should I wait a couple more days?..
