When is the latest you’ve got a BFP

I don’t know if this is the right group to post this, but I’m curious how long it took you to get a positive. I’m 4 days late but got a negative today. My boobs are sore and they’ve been sore for about a week and a half... maybe even two weeks, which is a normal period symptom for me, but my period is nowhere in sight. It should’ve come on Sunday. I’m never late. Usually right on time or a day early.
