4days late for AF, BFN!

Harriet
In need of some help ladies! 4days late for AF and having pregnancy symptoms such as nausea, vivid pregnancy dreams, lots of creamy/lotion cm, mild cramping, veiny bbs, hot flushes, gassy. I just feel pregnant. I had BFN on hpt with my first wee today. Has anyone else had the same? And still ended with a BFP
Thanks ladies xx
