5 days late - Negative tests

Ly

Hey y'all, my husband and I just started TTC baby #2 this August and my period was due to start Sept. 1st, so I'm 5 days late today & I've taken several tests, the last one was yesterday and it was still negative but my breasts are tender, like uncomfortably tender. Has anyone had this happen? Is it possible it's still too early to test?

I've read that it could be ectopic and it has me a bit worried. 😞
