13DPO 3ish days till AF...BFNs and pregnancy symptoms

October was the first month I got a positive ovulation test, we have been trying and off the pill since June...My periods are beginning to get regular-ish....but for the past 5 days I've experienced cramping, bloating, constipation, nausea, even cravings. People tell me that all these symptoms could be pregnancy symptoms but most are symptoms people didn't have till trimester 2...feeling frustrated and I just want a BFP :(
