I'm a compulsive tester and my period was due today. I've had bfn's for the last week and haven't had any symptoms to give me much hope- I really assumed AF was on the way. Today I had diarrhea all morning, have had a headache off and on for 3 days now, and lower back pain tonight. Still no breast tenderness or increase in urination frequency. How late did some of you get a BFP?? Anyone get one without these tell-tale symptoms? Thanks in advance!
