How long before a missed period will a blood test detect pregnancy?

Pregnancy. Great majority of pregnancies occur when coitus takes places within the 3 day interval just prior to ovulation. The first hormonal evidence of implantation (appearance of hcg) ocurred on 8 to 10 days after ovulation. Some commercial urine pregnancy test dont become positive until 5 days before your missed period. If negative and still suspect a pregnancy do a blood level pregnancy test.
