Hi! I am 35 years old with a regular cycle of 28 days. My husband and I have been trying to get pregnant for 3 years with no result. During my last ovulation, my husband and I did have intercourse. My period is not due for another 7 days. This morning, when I urinated, there was a blood clot approx. the size of a quarter (maybe larger?) with no menstrual bleeding. Should we be concerned? It is a Sunday, is a visit to the ER neccessary? It is too early for a pregnancy test, and I have had no other sign or symptoms of being pregnant (other than very tired last 2 days). I am very worried (and obviously tearful after trying to conceive for so long). Does anyone have any idea about this?
