My period began:19/06. lasted 7 days. 2 days later i had unprotected sex with withdrawal method. previous cycle length: 30 days. could i be pregnant?

Maybe. Maybe not.: It can be hard to guess if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A home urine pregnancy test gives a reliable result about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If a woman's normal, regular menstrual period comes, then she is not pregnant.
