help!

So I am currently pregnant, not sure when I got pregnant.  I had sex 6 days before my period, the test was extremely dark the day after my period was due. I had been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> and I ovulated 2 weeks before I had sex. I did have sex during that time also. Is it possible that I could have gotten pregnant from the sex 6 days before my period?
