well, you are not fully compatable with your eggs and/or you are not able to carry the egg and sperm just yet. it also could have ben the wrong time to have "tried".
If she went to the hospital, ask to see discharge papers. If it happened at home, ask if there was blood on the sheets and then see if your laundry detergent seem lower than before. I would wait a while and bring up the subject of babies and see if she seem like she wanted to have one. Her reaction can tell you if she really wanted a baby or not.

Yes, it is possible to have a miscarriage before you know you're pregnant. It happens a lot more than, I think, people know about. I think a doctor can do an exam to tell if you've had a miscarriage or not, but it probably has to be soon after. Call a doctor right away if you want to know. you could definatly have a misscarage before you know you are pregnant because some times you do have what you think are periods so you don't notice changes in your body. some people go full term with out knowing there are pregnant. but i don't think it is possible for a doctor to check if you have had a misscarge once the misscarage is complete.
