I'm on day 74 of my cycle, all urine tests have been BFN, I went to the dr. In July after I missed my 1st AF and they did a blood test and ultra sound which was also Negative. :( my SO and I have been trying for almost a year now and nothing like this has happened. I'm so confused! Is there ANY possibility that I could be pregnant? Has Anybody else experienced this???? Please Help!
