My husband and I are trying to conceive. The first day of my last period was June 20th. My ovulation test said I had a surge on July 17th, we had sex on July 16th and 17th. I have still not gotten my period. I have sore breast, frequent urination, very mild cramps and lower back pain that comes and goes, nausea, tiredness. I do not have any colored discharge or any bleeding at all. Just clear discharge. I have not had a positive pregnancy test though. Could I still be pregnant? What s going on?
