3 days late but BFN - so confused

JE

I’m just so confused 🙁 AF was due on Sunday and she never showed and still hasn’t showed. I’ve had symptoms that could be either AF or Early pregnancy except I never get any symptoms like this before my period. It usually just shows up on the 3rd of every month with no warning signs. I’ve had dull cramps, lower back pain, bloating after eating, dull headaches, watery CM and cold symptoms. I took a test this morning and it was a BFN. My period is usually short (about 4 ish days) so by now i’ve almost completely skipped it which has never happened before. I’m so confused and disappointed 😔
