My period is now 12 days late.. I went to the doctor Wednesday sept 14th (the day my period should have started) my periods are usually pretty regular. I went to the dr for what I thought was the beginning of a uti, they did a urine pregnancy test, negative, and sent me on my way with an antibiotic. Still no sign of period. No cramps or breast tenderness which I usually get! Not sure what to think???? Haven't tested since the doctor did! Any suggestions? Answers?? Thanks in advance!!!
