Your boyfriend has ejacualted in you twice this month could you be pregnant?

The chance of becoming pregnant depends largely on where you were in your menstrual cycle. The time you are most likely to become pregnant is half-way through your cycle, which is when you ovulate. For example, if you start your period every 28 days, then half-way though your cycle would be 14 days from the day you start. If you start your period every 32 days, then your highest chance of becoming pregnant would be 16 days from the first day of your period. The ovulation, which is when the ovaries release the egg for fertilization, usually lasts between 2 - 4 days, but can vary from one woman to another.
