I had my period nov 13th, i took 2 birth control pills the 5th and 6th day later to stop my period and didnt take any since. i had unprotected sex the 21st,27th&28th. what are my chances of being pregnant?

Hard to guess...: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
