I had a continuos pills for two months and i secided to take a 7 day break. on my 4th day break from pills i had unprotected sex. will i b pregnant?

Yes: As long as your break was no more than 7 days then you are still protected.

Not likely: But if you miss periods do pregnancy test. It will be unlikely that you ovulate 4 days after stopping the pills but is important to take meds as recommended for full benefit

Unlikely: if you miss a period take a pregnancy test. Take pills as directed by your doctor and consult the before stopping the medication. Use condoms as a backup measure.
