I had my period regular on the 16 ended 19th i had sex on the 23 unprotected i gave him oral before & he was in for a min....chances of pregnacy?

Always a chance...: 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 (when conception might have occurred), or 1 week after missing a period. An ob-gyn doctor can evaluate any persistent or worrisome symptoms.
