2 days late but got a BFN 3 days ago

Anne • Hi I`m anne. I`m 24, engaged and I`m pregnant
So I tested on Monday with a clear blue digital test but it was negative and still no AF. I can feel like I'm coming on with my pelvic pain I have when AF is due. I was 5 days late last cycle and it's never been like that before and it's happening again. I'm so confused on what to do or think :(
