When you are pregnant with 2 weeks, then you are not pregnant. 2 weeks pregnant is an ovulating week. (When you will come to know about your pregnancy, you would be probably around 4 weeks pregnant or may be 5 weeks pregnant.) Once the menstrual cycle is over, a new ovum/egg starts forming which results in Ovulation during this week. Ovulation is a time when a mature egg is released from an ovary, pushed down via Fallopian tube and is available to be fertilized.
