A clinical pregnancy is a pregnancy that is confirmed by both high levels of hCG (the pregnancy hormone) and ultrasound confirmation of a gestational sac or heartbeat (fetal pole).

Detecting a fetal heartbeat with a handheld Doppler or a fetoscope also clinically confirms a pregnancy.

Sometimes, a pregnancy ends in miscarriage before ultrasound confirmation can take place. This may be referred to as a chemical pregnancy.

Understanding the definitions and difference between a chemical pregnancy, a clinical pregnancy, and pregnancy symptoms can be confusing. Let\'s explore each, one by one.
