How soon after sex and ovulation can you tell or find out if ur preg. Without taking a test or having a period just yet?

Pregnancy. Sperm may reach fallopian tube in 30 min. Conception (pregnancy) depends on when you ovulate (you don't know that, you can only gess). Sperm may survive in fallopian tube for 7 days , ( even longer in rare ocassions) . So you can get pregnant in 30 minutes or 7 days after intercourse, it depends on when you ovulate. The answer is always on the pregnancy test.
You can't. There is no way to determine for sure if you are pregnant between ovulation and the start of the next period, except with a sensitive pregnancy test. If i misunderstood your question, please feel free to ask again.
