Late period, no BFP yet

So I am currently 4 days late for my period . Sore lower back , acne like a high schooler , sore boobs , lack of appetite. No cramps or headaches like usual , but I took a test first thing in the morning and it was negative .

How long did it take you if you tend to have a longer cycle ( I used to be 28 on BC, now I’m 28 & up ) for you to get a positive ? Did anyone else have similar symptoms before BFP? :)
