I am currently on yasmin. i took the first 2 pills of a new pack but then missed about 5 pills after. i had unprotected sex the weekend before i started the new pack. what are my chances of pregnancy?

Unlikely, but...: It can be hard to guess whether a woman is pregnant or not. A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a withdrawal period, or after having a "weird" period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.
