What are the chances i could be pregnant if i had sex 6 days before ovulation and time before that i had sex last day of my period?

Can do preg. test: 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 possible conception), or 1 week after missing a period. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
