So I took HPT 4 days ago an got a BFN yesterday my period was due but never came an so far today nothing either. Since my wedding I had been tracking an it was ALWAYS on time. DPO I had symptoms of cramping, headache and nausea now nothing I don't feel like AF is going to come. And this morning had green stool which I never get! Did this happen to anyone an they got BFP?
