Hello. I have read your message. I think you need to understand that to get pregnant, you will need to have an ovum (female fertile cell) and a sperm (male fertile cell) in the uterine cavity . Presence of just one is not enough to get pregnant. Now that we know that he ejaculated in your vaginal cavity, we know that the sperm is present. However, from the query, I have no way of telling whether you have a ovum in the uterine cavity. For that, you need to assess your menstrual cycle. In a normal and regular 28 day cycle, the ovum is usually present on the 14th day of the cycle. So you need to calculate the possibility of the ovum being present. If there is a chance that the ovum is present, there is a possibility for pregnancy. I have tried to make it as simple as possible. I hope that you find the information useful. Feel free to contact me for any further query that you may have. Best wishes, Dr Mittal
