3-4 days late, negative.. when to test again?

Hey ladies,

So I've taken a clearblue test 1 day being late and got a negative , (two days ago)

I am now three days late and not sure how long to wait to try again, ( I have a regular cycle of 27 days and have never been late except when I was pregnant)

But I got a positive a day before my period showed so Idk wether to believe the negative or not.

I have been peeing a lot,

have had cramps in the last few days,

have white/creamy cm but not a lot lately,

my boobs have been a little sore and my nipples seem darker, and I'm eating like crazy it's ridiculous 🙄😂

When should I test? I'm thinking maybe in the morning?

And could I of gotten a false negative or has anyone else??

Not knowing is killing me 🙄😪

Opinions and experiences please?!
