Will I still get pregnant?

My partner and I have had sex almost everyday since Friday (multiple sessions😏) and today around 2est I took a opk which was positive. My partner won’t be home for another 3 days. Are my chances good that I’ll get pregnant? Today, right after sex I waited maybe 10 minutes and took the opk and my test line was darker than the control line! We really want to expand our family. Please help.
