Latest You Received A BFP After BFNs

I’ve been having many pregnancy symptoms such as vivid dreams(even dreamed about fish one night), nausea, sore breast on and off, super sensitive nipples, VERY frequent urination, stuffy nose, hiccups, super gassy, on and off appetite, etc. I tested negative 4 times, 23 days late being my latest test.. My cycle is EXTREMELY regular and I’ve never in my life missed a period.. Is there a possibility I’m pregnant? Currently 26 days late.. *UPDATE* My period eventually came after being a month and a half late.
